Dat ene getal verklaart bijna alles eraan. Met minder magnesium ruilt 5005 de hoge sterkte van zijn 5xxx-neven in voor twee dingen waarvoor kopers het daadwerkelijk specificeren: <strong>een uitstekende anodiseerrespons<\/strong> en <strong>corrosieweerstand dicht bij die van 3003 bij een lager gewicht aan legeringselementen<\/strong>. Het is de standaardkeuze voor geanodiseerd architecturaal plaatmateriaal, en de mechanische eigenschappen liggen in dezelfde band als 3003 in plaats van in structureel gebied.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Het is een niet-warmtebehandelbare legering. Elke toename van sterkte komt van koudvervorming, tot uitdrukking gebracht in de H-tempers, en het kan niet precipitatief worden gehard zoals 6061 of 7075. De praktische consequentie is dat hardheid en sterkte worden bepaald door de temper die u koopt, niet door wat u daarna met het onderdeel doet \u2014 behalve het teruggloeien.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Er is ook een echt voordeel dat over het hoofd wordt gezien: omdat 5005 ruim onder de drempel van ~3% magnesium ligt, is het <strong>niet<\/strong> gevoelig voor \u03b2-fase (Al\u2083Mg\u2082) korrelgrensprecipitatie die hogere-magnesiumgraden zoals 5083 en 5056 beperkt tot ruwweg 65 \u00b0C bij langdurige dienst. Voor warme, mild corrosieve toepassingen draagt 5005 die beperking niet.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Chemische samenstelling van 5005<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Samenstellingsgrenzen volgens ASTM B209 \/ EN 573-3, in gewichtsprocent. Magnesium is het enige bewuste legeringselement van betekenis; al het andere is ofwel een kleine gecontroleerde toevoeging of een onzuiverheidsplafond.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Element<\/th><th>Inhoud (%)<\/th><th>Rol<\/th><\/tr><\/thead><tbody><tr><td>Magnesium (Mg)<\/td><td>0.50 \u2013 1.10<\/td><td>Primair legeringselement; sterkte en corrosiegedrag<\/td><\/tr><tr><td>Silicium (Si)<\/td><td>0,30 max<\/td><td>Onzuiverheid, laag gehouden voor anodiseerhelderheid<\/td><\/tr><tr><td>IJzer (Fe)<\/td><td>0,70 max<\/td><td>Onzuiverheid; be\u00efnvloedt oppervlakteafwerking<\/td><\/tr><tr><td>Koper (Cu)<\/td><td>maximaal 0,20<\/td><td>Laag gehouden om corrosieweerstand en anodische kleur te beschermen<\/td><\/tr><tr><td>Mangaan (Mn)<\/td><td>maximaal 0,20<\/td><td>Kleine toevoeging, korrelstructuur<\/td><\/tr><tr><td>Chroom (Cr)<\/td><td>0,10 max<\/td><td>Kleine toevoeging voor corrosieweerstand<\/td><\/tr><tr><td>Zink (Zn)<\/td><td>0,25 max<\/td><td>Sporen<\/td><\/tr><tr><td>Titanium (Ti)<\/td><td>0.05 \u2013 0.15<\/td><td>Korrelverfijner<\/td><\/tr><tr><td>Overige (per stuk)<\/td><td>0,05 max<\/td><td>Sporen van onzuiverheden<\/td><\/tr><tr><td>Overige (totaal)<\/td><td>0,15 max<\/td><td>Som van spore-onzuiverheden<\/td><\/tr><tr><td>Aluminium (Al)<\/td><td>Rest<\/td><td>Basismetaal<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">De strakke plafonds voor koper en silicium zijn belangrijker dan ze lijken. Beide elementen verkleuren een anodische film \u2014 koper duwt deze naar geel, silicium naar grijs \u2014 daarom maakt een low-Cu, low-Si chemie van 5005 een anodiseerlegering in plaats van zomaar een andere 5xxx-graad.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hardheid van 5005 per temper<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hardheid is waar de koudvervormde structuur van 5005 het meest direct tot uiting komt. Onderstaande waarden zijn typische Brinell-cijfers gemeten met een belasting van 500 kg en een kogel van 10 mm (ASTM E10), de conventie die voor gewalst aluminium wordt gebruikt.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Temper<\/th><th>Toestand<\/th><th>Brinell-hardheid (HB)<\/th><th>Geschatte schuifsterkte (MPa)<\/th><\/tr><\/thead><tbody><tr><td>O<\/td><td>Uitgegloeid<\/td><td>28<\/td><td>76<\/td><\/tr><tr><td>H32<\/td><td>Vervormingsgehard, gestabiliseerd (\u00bc hard)<\/td><td>36<\/td><td>96<\/td><\/tr><tr><td>H34<\/td><td>Vervormingsgehard, gestabiliseerd (\u00bd hard)<\/td><td>41<\/td><td>96<\/td><\/tr><tr><td>H36<\/td><td>Vervormingsgehard, gestabiliseerd (\u00be hard)<\/td><td>46<\/td><td>103<\/td><\/tr><tr><td>H38<\/td><td>Vervormingsgehard, gestabiliseerd (volhard)<\/td><td>51<\/td><td>110<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Drie dingen volgen uit die tabel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Het bereik is smal.<\/strong> Over het gehele temperbereik beweegt 5005 zich van 28 naar 51 HB \u2014 minder dan een verdubbeling van gegloeid tot volhard. Vergelijk dat met 6061, dat ruwweg verdrievoudigt van O naar T6. Als uw ontwerp hardheid vereist die koudvervorming niet kan leveren, is 5005 het verkeerde uitgangspunt en geen enkele temperselectie lost dat op.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hardheid is een ontvangstinspectiegereedschap, geen ontwerpinvoer.<\/strong> HB is snel en niet-destructief genoeg om een levering tegen zijn MTC te controleren, en het correleert goed met treksterkte. Maar geen enkele ingenieur dimensioneert een beugel op basis van Brinell. Gebruik HB om te bevestigen dat u de bestelde temper hebt ontvangen; gebruik trek- en vloeigrens voor de daadwerkelijke berekening.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Anodiseren verandert de oppervlaktehardheid, niet de bulkhardheid.<\/strong> Dit is het meest voorkomende misverstand bij een hardheidsvraag. De anodische oxidelaag is veel harder dan het substraat \u2014 aluminiumoxide staat ver boven elke aluminiumlegering op de hardheidsschaal \u2014 dus kras- en slijtvastheid verbeteren aanzienlijk. Het onderliggende metaal is onveranderd, en een 5005-H34 plaat heeft nog steeds 41 HB onder zijn coating. Als een tekening \u201charder\u201d zegt, stel dan vast of het oppervlakteslijtvastheid betekent (anodiseer het) of draagvermogen (verander de legering).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Mechanische eigenschappen van 5005 per temper<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Typische waarden voor plaat en dikplaat. Let op dat ASTM B209 <em>minimum<\/em> waarden onder deze cijfers liggen en vari\u00ebren met dikte \u2014 gegarandeerde getallen voor uw specifieke partij komen uit de MTC, niet uit deze tabel.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Temper<\/th><th>Treksterkte (MPa)<\/th><th>Rekgrens (MPa)<\/th><th>Rek (1% in 50 mm)<\/th><th>Hardheid (HB)<\/th><\/tr><\/thead><tbody><tr><td>O<\/td><td>124<\/td><td>41<\/td><td>25<\/td><td>28<\/td><\/tr><tr><td>H32<\/td><td>138<\/td><td>117<\/td><td>11<\/td><td>36<\/td><\/tr><tr><td>H34<\/td><td>159<\/td><td>138<\/td><td>8<\/td><td>41<\/td><\/tr><tr><td>H36<\/td><td>179<\/td><td>165<\/td><td>6<\/td><td>46<\/td><\/tr><tr><td>H38<\/td><td>200<\/td><td>186<\/td><td>6<\/td><td>51<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">De rek-kolom is degene die de meeste echte specificaties bepaalt. Van H32 naar H38 gaan levert ruwweg 45% meer treksterkte op en kost u bijna de helft van de beschikbare rek \u2014 11% naar 6%. Voor een vlak decoratief paneel is die ruil gratis. Voor alles met een vormradius, een zoom of een gerolde rand is H32 of H34 het plafond, en O is het antwoord wanneer het vormen ernstig is.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De aanduidingen H1x en H3x zijn niet uitwisselbaar. H1x-tempers zijn alleen vervormingsgehard; H3x-tempers zijn vervormingsgehard <em>en vervolgens<\/em> gestabiliseerd met een lage-temperatuur warmtebehandeling, die een beetje sterkte afhaalt en betekenisvolle ductiliteit teruggeeft. Die stabilisatie is waarom H32\/H34 het architecturale werk domineren \u2014 de extra ductiliteit koopt vormbaarheid, en de gestabiliseerde toestand houdt zijn eigenschappen vast in plaats van age-softening op de plank.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Fysische eigenschappen van 5005<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Eigendom<\/th><th>Waarde<\/th><\/tr><\/thead><tbody><tr><td>Dichtheid<\/td><td>2,70 g\/cm\u00b3<\/td><\/tr><tr><td>Smelttraject<\/td><td>632 \u2013 655 \u00b0C<\/td><\/tr><tr><td>Thermische geleidbaarheid<\/td><td>~201 W\/m\u00b7K (O-temper)<\/td><\/tr><tr><td>Elektrische geleidbaarheid<\/td><td>~52% IACS (neemt af in hardere tempers)<\/td><\/tr><tr><td>Thermische uitzettingsco\u00ebffici\u00ebnt<\/td><td>23,7 \u00d7 10\u207b\u2076 \/\u00b0C (20\u2013100 \u00b0C)<\/td><\/tr><tr><td>Specifieke warmtecapaciteit<\/td><td>~900 J\/kg-K<\/td><\/tr><tr><td>Elasticiteitsmodulus<\/td><td>~69 GPa<\/td><\/tr><tr><td>Poissonratio<\/td><td>0.33<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Twee hiervan hebben inkoopgewicht. Thermische en elektrische geleidbaarheid bij ~201 W\/m\u00b7K en ~52% IACS zijn hoog voor een 5xxx-legering \u2014 het lage magnesiumgehalte is de reden \u2014 en beide nemen af naarmate de temperhardheid stijgt, dus een geleidbaarheidsgestuurde specificatie moet tegen de O- of H32-toestand worden geplaatst in plaats van over het hele bereik te worden aangenomen. Het smeltbereik is vooral van belang voor lassen en elke discussie over dienst bij verhoogde temperatuur.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Corrosieweerstand en anodiseren<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Atmosferische en mild alkalische dienst.<\/strong> 5005 resists general atmospheric corrosion comparably to 3003, including industrial and coastal atmospheres, with the added 5xxx advantage of better performance in slightly alkaline conditions. It is not the choice for continuous seawater immersion \u2014 5083 and 5086 hold that ground \u2014 but for marine <em>atmosphere<\/em>, coastal architecture, and interior boat hardware it is comfortably adequate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The 65 \u00b0C question.<\/strong> Higher-magnesium 5xxx grades carry a sustained-service ceiling near 65 \u00b0C, above which \u03b2-phase precipitation along grain boundaries opens a stress-corrosion-cracking path. At ~0.8% Mg, 5005 is below the threshold where that mechanism is a practical concern. This is a real differentiator against 5083 and 5056 in warm service, and it is one of the least-appreciated reasons to pick it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Elevated temperature still softens it.<\/strong> Cold-worked tempers lose strength progressively as service temperature rises, with full annealing around 345 \u00b0C. If a part will see sustained heat, design against the annealed (O-temper) values rather than the H-temper values on the order \u2014 the cold work you paid for does not survive the heat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Anodizing \u2014 and the catch.<\/strong> When anodized, 5005 produces a clear, homogeneous film that is more transparent than 3003&#8217;s and gives an excellent colour match to 6063 architectural extrusions. That combination is why it is the default for anodized fa\u00e7ades and decorative trim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The catch: 5005 can anodize with visible streaking, sometimes called &#8220;barcoding&#8221;. If the finish is critical \u2014 a fa\u00e7ade panel in full view, a large uninterrupted surface \u2014 specify <strong>5005-AQ<\/strong> (anodising quality, sometimes sold as special anodising quality) at the time of order. It costs more and it is far cheaper than discovering the streaks after installation. Galvanic corrosion is the other standing caveat: like any aluminium, 5005 corrodes rapidly when electrically coupled to a more noble metal in a wet environment, so isolate it from steel and copper alloys.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Working With 5005<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-5005.png\" alt=\"\" class=\"wp-image-10592\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-5005.png 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-5005-300x225.png 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-5005-768x576.png 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-5005-16x12.png 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-5005-600x450.png 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Vormen.<\/strong> 5005 forms readily, especially annealed. Thin H32 sheet can be bent to very tight radii \u2014 roughly 0 to \u00bd \u00d7 thickness \u2014 without failure, and H34 generally manages 1 to 2 \u00d7 thickness. Deep drawing, spinning, and roll forming are standard in the O condition. Forming loads and tool wear are lower than for carbon steel on comparable geometry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Lassen.<\/strong> GTAW (TIG) and GMAW (MIG) both run cleanly, as does resistance spot welding and friction stir welding. Filler choice splits by priority: <strong><a href=\"https:\/\/premiumalu.com\/nl\/product\/4043-aluminiumlegering\/\" data-type=\"product\" data-id=\"8585\">4043<\/a><\/strong> (Al-Si) is often preferred for its hot-cracking tolerance and weld-bead fluidity, while <strong><a href=\"https:\/\/premiumalu.com\/nl\/product\/5356-aluminiumlegering\/\" data-type=\"product\" data-id=\"8837\">5356<\/a><\/strong> (Al-Mg) produces mechanically stronger weld metal. Neither requires pre- or post-weld heat treatment, and the low magnesium content means there is no meaningful post-weld sensitization risk. Expect the heat-affected zone to revert toward annealed strength \u2014 as with every non-heat-treatable alloy, that strength is not coming back.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bewerking.<\/strong> Fair. 5005 machines better than very soft grades such as 1100 or 3003 and less well than free-cutting alloys such as 2017 or 6082. Its softness produces gummy chips and built-up edge, so use sharp tooling, higher cutting speeds, and generous lubrication. Where a part is machining-dominated rather than finish-dominated, 6061 is the better call.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Annealing.<\/strong> Standard treatment is around 345 \u00b0C followed by slow cooling. It is not generally hot worked \u2014 forging is rarely applied to 5xxx alloys and is not a normal route for 5005.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5005 vs 3003 vs 5052 vs 6061<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/5005-vs-3003-5052-and-6061-Applications.png\" alt=\"\" class=\"wp-image-10591\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/5005-vs-3003-5052-and-6061-Applications.png 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/5005-vs-3003-5052-and-6061-Applications-300x225.png 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/5005-vs-3003-5052-and-6061-Applications-768x576.png 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/5005-vs-3003-5052-and-6061-Applications-16x12.png 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/5005-vs-3003-5052-and-6061-Applications-600x450.png 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Legering en tempering<\/th><th>Treksterkte (MPa)<\/th><th>Rekgrens (MPa)<\/th><th>Rek (%)<\/th><th>Hardheid (HB)<\/th><th>Anodiseren<\/th><th>Geschikt voor<\/th><\/tr><\/thead><tbody><tr><td><strong><a href=\"https:\/\/premiumalu.com\/nl\/product\/5005-aluminiumlegering\/\" data-type=\"product\" data-id=\"7797\">5005-H34<\/a><\/strong><\/td><td>159<\/td><td>138<\/td><td>8<\/td><td>41<\/td><td>Excellent \u2014 clear film, matches 6063<\/td><td>Anodized architectural panels, signage<\/td><\/tr><tr><td><strong><a href=\"https:\/\/premiumalu.com\/nl\/product\/3003-aluminiumlegering\/\" data-type=\"product\" data-id=\"2929\">3003-H14<\/a><\/strong><\/td><td>152<\/td><td>145<\/td><td>8\u201316<\/td><td>40<\/td><td>Good \u2014 may discolour slightly<\/td><td>Kookgerei, dakbedekking, algemeen plaatwerk<\/td><\/tr><tr><td><strong><a href=\"https:\/\/premiumalu.com\/nl\/product\/5052-aluminiumlegering\/\" data-type=\"product\" data-id=\"2936\">5052-H32<\/a><\/strong><\/td><td>228<\/td><td>193<\/td><td>12<\/td><td>60<\/td><td>Fair \u2014 less uniform<\/td><td>Marine parts, fuel tanks, formed enclosures<\/td><\/tr><tr><td><strong><a href=\"https:\/\/premiumalu.com\/nl\/product\/6061-aluminium-plaat\/\" data-type=\"product\" data-id=\"8950\">6061-T6<\/a><\/strong><\/td><td>310<\/td><td>276<\/td><td>12<\/td><td>95<\/td><td>Good \u2014 slightly less uniform<\/td><td>Structural frames, extrusions, machined parts<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>5005 vs 3003.<\/strong> At comparable temper these two are close on strength \u2014 within a few percent \u2014 so anyone choosing between them on strength is optimising the wrong variable. 5005 wins on anodizing clarity, colour match to 6063, and conductivity (~52% IACS against ~40%). 3003 wins on price and marginally better deep-drawing.

Its hardness window is narrow by design (28 HB annealed to 51 HB full hard), and the temper choice is where specs live or die: H32\/H34 for formed parts, H38 only when nothing forms, and 5052 or 6061 the moment load-bearing, immersion service, or machining volume becomes the driver. If the surface is visible and exposed, spend the small premium on 5005-AQ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At Linsy Aluminum, we supply 5005 across sheet, coil, plate, bar, tube, and wire in the common tempers, with in-house machining, welding, laser cutting, anodizing, and polishing. Send your drawing and spec \u2014 temper and anodizing requirement included \u2014 and we&#8217;ll confirm hardness and finish before you commit.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Veelgestelde vragen<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How hard is 5005 aluminum?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It depends entirely on temper, because 5005 is non-heat-treatable and gains hardness only from cold work. Typical Brinell values run 28 HB in the annealed O condition, 36 HB in H32, 41 HB in H34, 46 HB in H36, and 51 HB in H38. Published figures vary somewhat by source and thickness, so treat these as typical and confirm guaranteed values on the MTC.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Kan aluminium 5005 een warmtebehandeling ondergaan?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. 5005 cannot be precipitation-hardened; all strength comes from strain hardening, expressed in the H-tempers. It can be annealed \u2014 around 345 \u00b0C followed by slow cooling \u2014 but that softens it rather than strengthening it. If you need heat-treatable strength, 6061 is the usual move.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which 5005 temper should I specify?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use O when the part is deeply drawn or severely formed. H32 is the general-purpose choice and the safest default for architectural sheet, with H34 adding strength where some formability can be given up. H36 and H38 deliver maximum strength but elongation drops to around 6%, which rules out most forming. H32 and H34 are preferred for anodized architectural work because the stabilised H3x condition holds its properties.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does anodizing make 5005 harder?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It hardens the surface, not the metal. The anodic oxide layer is considerably harder than the aluminium substrate, so scratch and wear resistance improve substantially \u2014 but the bulk hardness underneath is unchanged, and a 5005-H34 part still has 41 HB below its coating. Anodizing is the right answer for surface durability and the wrong answer for load-bearing capacity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is 5005 suitable for marine environments?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For marine atmosphere, yes \u2014 it performs well in coastal and salt-spray exposure and is widely used for interior boat fittings and coastal architectural parts. For continuous seawater immersion or heavily loaded marine structure, higher-magnesium grades such as 5083 or 5086 are the correct specification. 5005 also has an advantage here: at ~0.8% Mg it sits below the threshold where the 65 \u00b0C sensitization and stress-corrosion-cracking limit applies to grades like 5083 and 5056.<\/p>","protected":false},"excerpt":{"rendered":"<p>What Is 5005 Aluminum? 5005 is the lean-magnesium end of the 5xxx family, carrying roughly 0.8% magnesium \u2014 well below 5052 (~2.5%) or 5083 (~4.5%).
