Het bevat ongeveer 5% magnesium, waardoor de chemie dicht bij de 5xxx plaat- en plaatlegeringen ligt waarvoor het is ontworpen om te verbinden \u2014 5083, 5086, 5056, 5454 en 5456.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Die magnesiumovereenkomst is het hele punt. Wanneer u een 5xxx-basismetaal last, is het lasbad een mengsel van toevoegmateriaal en gesmolten moedermetaal. Als het toevoegmateriaal chemisch dicht bij het moedermetaal ligt, gedraagt de voltooide las zich als de rest van het onderdeel: vergelijkbare sterkte, vergelijkbaar corrosiepotentieel, vergelijkbare reactie op anodiseren. Als dat niet het geval is, wordt de las de zwakke schakel \u2014 of de plek waar corrosie begint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Een verduidelijking die van belang is voor specificatie: 5356 is geregistreerd als een wrought-legering en verschijnt in staafl-, stang- en draadnormen, maar in de praktijk gaat essentially alle geproduceerde 5356 naar lastoevoegmateriaal. Het is geen structurele kwaliteit. U zult 5356 niet als structurele plaat gespecificeerd zien worden zoals u 5083-H116 of 5456-H116 ziet. Waar 5356 in staafvorm verschijnt, is het staaf bestemd om toevoegmateriaal te worden of te voeden.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Specificaties en equivalente aanduidingen<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Een \u201cspecificaties\u201d-vraag moet beginnen met de werkelijke specificatienummers, want dat is wat op een WPS en een inkooporder komt.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Standaard<\/th><th>Benaming<\/th><\/tr><\/thead><tbody><tr><td>AWS A5.10 (VS)<\/td><td>ER5356<\/td><\/tr><tr><td>EN ISO 18273 (Europa)<\/td><td>S Al 5356 (AlMg5Cr(A))<\/td><\/tr><tr><td>DIN 1732 (erfenis Duits)<\/td><td>3.3556<\/td><\/tr><tr><td>JIS Z 3232 (Japan)<\/td><td>A5356-WY (draad) \/ A5356-BY (staaf)<\/td><\/tr><tr><td>Legeringfamilie<\/td><td>5xxx, Al-Mg, niet-warmtebehandelbaar<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Goedkeuringen van classificatiemaatschappijen zijn doorgaans beschikbaar op commerci\u00eble draad van grote toevoegmateriaalfabrikanten \u2014 ABS, BV, LR, DNV, T\u00dcV en DB verschijnen op ER5356-datasheets.

MIG-draad wordt normaal hardgetrokken geleverd, en dat is gunstig: 5356 is stijver dan de siliciumtoevoegmaterialen, en die kolomsterkte is waarom het betrouwbaarder door een MIG-pistool voedt dan ER4043.

For a structural joint, design against the allowable stresses in the applicable code \u2014 AWS D1.2 for aluminum structures in the US, or the relevant EN or class-society rule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The headline is that 5356 gives roughly 50% more as-welded tensile strength than 4043. That is the reason it is the default structural filler for 5xxx work.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why 5356 Matches 5xxx Base Metals<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Three mechanisms, in order of how often they decide the job.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Corrosion compatibility.<\/strong> The weld bead and the parent plate sit in the same electrolyte. If their corrosion potentials differ, one becomes the anode and corrodes preferentially. Filling a high-magnesium plate such as <a href=\"chrome-extension:\/\/cbgfjbdckbpenliighcjcbjfiihnnkfe\/markdown.html?originUrl=file%3A%2F%2F%2FUsers%2Fjaven%2FDesktop%2FAluminum%2FAluminum%25E6%2596%2587%25E7%25AB%25A0%2F%25E7%25AC%25AC%25E4%25BA%258C%25E8%25BD%25AE%25E4%25BC%2598%25E5%258C%2596%2F5356-aluminum-filler-comprehensive-guide.md\">5083-H321<\/a> with a magnesium-matched filler keeps the weld zone close to the parent in potential, so the joint does not become a built-in corrosion site.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Avoiding brittle intermetallics.<\/strong> Silicon-bearing filler diluted into a high-magnesium base forms Mg\u2082Si in the weld metal. In quantity it reduces ductility and makes the joint brittle. The low silicon cap on 5356 is there to prevent exactly that.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Anodizing consistency.<\/strong> A magnesium-rich bead anodizes to a light, near-white finish that is close to the 5xxx parent plate. Silicon fillers go dark gray to black. Where appearance is a specification line, this decides the filler on its own.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5356 vs 4043: How to Choose<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the single most common filler decision in aluminum fabrication. The silicon side of the same decision is covered in our <a href=\"chrome-extension:\/\/cbgfjbdckbpenliighcjcbjfiihnnkfe\/markdown.html?originUrl=file%3A%2F%2F%2FUsers%2Fjaven%2FDesktop%2FAluminum%2FAluminum%25E6%2596%2587%25E7%25AB%25A0%2F%25E7%25AC%25AC%25E4%25BA%258C%25E8%25BD%25AE%25E4%25BC%2598%25E5%258C%2596%2F5356-aluminum-filler-comprehensive-guide.md\">4043 filler guide<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Factor<\/th><th>ER5356<\/th><th>ER4043<\/th><\/tr><\/thead><tbody><tr><td>Filler system<\/td><td>Al-5%Mg<\/td><td>Al-5%Si<\/td><\/tr><tr><td>Best-matched base metals<\/td><td>5xxx with &gt;3% Mg (5083, 5086, 5456, 5056)<\/td><td>6xxx (6061, 6063), castings (A356, 319)<\/td><\/tr><tr><td>As-welded tensile<\/td><td>250 \u2013 300 MPa<\/td><td>165 \u2013 200 MPa<\/td><\/tr><tr><td>Schuifsterkte<\/td><td>Hoger<\/td><td>Onder<\/td><\/tr><tr><td>Hot-cracking resistance<\/td><td>Goed<\/td><td>Beter<\/td><\/tr><tr><td>Puddle fluidity<\/td><td>Lower \u2014 5356 does not wet out as easily<\/td><td>Higher, easier bead control<\/td><\/tr><tr><td>Solidification range<\/td><td>Wider<\/td><td>Narrower, which is why it cracks less<\/td><\/tr><tr><td>Anodized color<\/td><td>Light, matches 5xxx parent<\/td><td>Dark gray to black<\/td><\/tr><tr><td>Marine corrosion match with 5xxx<\/td><td>Goed<\/td><td>Poor \u2014 avoid<\/td><\/tr><tr><td>Sustained service above 65 \u00b0C<\/td><td><strong>Nee<\/strong><\/td><td>Ja<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The working rule: match the filler magnesium level to the base metal. High-magnesium base, ambient service \u2192 5356. 6xxx base \u2192 4043 or 5356 depending on whether crack resistance or anodizing matters more. Castings \u2192 4043. Sustained heat \u2192 4043, or better, a low-magnesium 5xxx filler.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One caution on the marine case. The failure mode people describe \u2014 a 4043 weld corroding preferentially on a 5xxx hull \u2014 is real and well documented in boat construction, but the polarity of that couple depends on the exact dilution and is not something to state as a universal rule. The safe and defensible statement is that the electrochemical mismatch makes the weld zone the likely attack site in saltwater, and that is reason enough to avoid it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other 5xxx Fillers: 5183, 5556, and 5554<\/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\/2026\/11\/5356-aluminum-filler-comparison.webp\" alt=\"5356-aluminum-filler-comparison\" class=\"wp-image-10803\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-filler-comparison.webp 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-filler-comparison-300x225.webp 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-filler-comparison-768x576.webp 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-filler-comparison-16x12.webp 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-filler-comparison-600x450.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">5356 is the general-purpose option, not the only one. When you are welding high-magnesium plate, these three come up regularly.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Vulstof<\/th><th>Mg %<\/th><th>Mn %<\/th><th>Use it when<\/th><\/tr><\/thead><tbody><tr><td>ER5356<\/td><td>4.5 - 5.5<\/td><td>0.05 - 0.20<\/td><td>Default for 5xxx base metals; best combination of strength, feedability and finish<\/td><\/tr><tr><td>ER5183<\/td><td>4.3 \u2013 5.2<\/td><td>0.50 \u2013 1.00<\/td><td>5083 and similar high-strength marine plate where the WPS calls for a manganese-bearing filler<\/td><\/tr><tr><td>ER5556<\/td><td>4.7 - 5.5<\/td><td>0.50 \u2013 1.00<\/td><td>Highest-strength 5xxx filler; specified for 5456 and heavy high-Mg weldments<\/td><\/tr><tr><td>ER5554<\/td><td>2.4 \u2013 3.0<\/td><td>0.50 \u2013 1.00<\/td><td><strong>Sustained service above 65 \u00b0C<\/strong> \u2014 the magnesium stays under the 3% SCC threshold<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The trade-off with ER5554 is strength. It is deliberately weaker, which is the price of staying below the magnesium threshold that makes the other three unsuitable for warm service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ER4943 is a newer aluminum-silicon-magnesium filler worth knowing about. It is a modification of 4043 developed for higher as-welded strength while keeping 4043-level crack resistance, and it is increasingly specified for 6xxx production welding. Color match after anodizing can be less predictable than with 5356, so test it if appearance matters.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The 65 \u00b0C Limit: Stress Corrosion Cracking<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the limitation that catches people out, and it is the one that should be checked first on any 5356 specification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Any aluminum alloy containing more than 3% magnesium is susceptible to stress corrosion cracking. That includes the 5xxx base metals such as 5083 and 5086 \u2014 and it includes almost all the common 5xxx fillers: <strong>5356, 5183 and 5556 all exceed the threshold.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Four conditions have to line up:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>The alloy contains at least 3% magnesium.<\/li>\n\n\n\n<li>A tensile stress is present. Weld residual stress is almost always enough.<\/li>\n\n\n\n<li>An electrolyte is available \u2014 salt water, for example.<\/li>\n\n\n\n<li>The joint has been held above roughly 65 \u00b0C (150 \u00b0F) long enough for the microstructure to sensitize.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">They do not all need to happen at the same time. Once the joint has seen elevated temperature, \u03b2-phase (Al\u2083Mg\u2082) has precipitated along the grain boundaries and the microstructure is sensitized. Dropping the temperature afterwards does not undo it \u2014 given stress and an electrolyte, cracking can still follow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical consequences:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Do not specify ER5356 for components running continuously above 65 \u00b0C. Engine brackets, heat exchangers, exhaust-adjacent parts and warm process lines fall in this category.<\/li>\n\n\n\n<li>If you need a 5xxx filler at elevated temperature, use <strong>ER5554<\/strong> \u2014 it is formulated to stay under 3% magnesium. Accept the lower strength.<\/li>\n\n\n\n<li>For 6xxx alloys in elevated service, ER4043 is usually the better answer.<\/li>\n\n\n\n<li>This applies to the base metal too. High-magnesium plate such as 5083 or 5456 should not be used above 65 \u00b0C regardless of what it is welded with.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">There is a specific trap here that is worth naming because it is easy to walk into. <strong>5454 is selected precisely because it tolerates elevated-temperature service.<\/strong> If you weld <a href=\"chrome-extension:\/\/cbgfjbdckbpenliighcjcbjfiihnnkfe\/markdown.html?originUrl=file%3A%2F%2F%2FUsers%2Fjaven%2FDesktop%2FAluminum%2FAluminum%25E6%2596%2587%25E7%25AB%25A0%2F%25E7%25AC%25AC%25E4%25BA%258C%25E8%25BD%25AE%25E4%25BC%2598%25E5%258C%2596%2F5356-aluminum-filler-comprehensive-guide.md\">5454<\/a> with ER5356 and then put it into warm service, the filler reintroduces the problem the base metal was chosen to avoid. For 5454 vessels or tanks designed to run hot, specify ER5554.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Welding Does to the Base Metal<\/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\/2026\/11\/5356-aluminum-heat-affected-zone.webp\" alt=\"5356-aluminum-heat-affected-zone\" class=\"wp-image-10802\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-heat-affected-zone.webp 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-heat-affected-zone-300x225.webp 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-heat-affected-zone-768x576.webp 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-heat-affected-zone-16x12.webp 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-heat-affected-zone-600x450.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Filler strength is only half the joint. The other half is what the arc does to the parent plate, and on non-heat-treatable 5xxx alloys that is a real strength loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The heat-affected zone of a welded 5xxx joint is effectively annealed. Strain-hardened tempers \u2014 H116, H321, H32 \u2014 lose their work hardening in the HAZ, and because the alloy is non-heat-treatable, that strength cannot be brought back by post-weld heat treatment. A 5083-H116 plate carries a specified minimum yield of 215 MPa under ASTM B928 (228 MPa is typical); in the HAZ the yield drops back toward annealed values, a loss of roughly 35\u201345%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Design accordingly: use the annealed allowable stresses from AWS D1.2 (or the applicable code) for the HAZ rather than the parent-metal temper values. The same principle applies to 6061-T6, where the HAZ overages and softens even though the filler choice is different.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Practical Welding Notes<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-cleaning-and-handling.webp\" alt=\"5356-aluminum-cleaning-and-handling\" class=\"wp-image-10804\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-cleaning-and-handling.webp 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-cleaning-and-handling-300x225.webp 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-cleaning-and-handling-768x576.webp 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-cleaning-and-handling-16x12.webp 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/5356-aluminum-cleaning-and-handling-600x450.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Most 5356 problems on the shop floor are feeding and cleanliness issues, not metallurgy.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Artikel<\/th><th>Recommendation<\/th><\/tr><\/thead><tbody><tr><td>Shielding gas<\/td><td>100% argon for most work; argon\/helium mixtures for thicker sections<\/td><\/tr><tr><td>Polarity<\/td><td>MIG: DCEP.

A 5356 bead anodizes to a light, slightly gray finish that sits close to a 5xxx parent plate. A 4043 bead goes dark gray to near black, because the silicon in the weld metal does not anodize the way the surrounding aluminum does.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For architectural or decorative work where color match is on the drawing, do not rely on the general rule alone. Run a coupon through the actual anodizing line with the actual filler lot and approve the sample before production.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Go\/No-Go: When to Specify 5356<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Go \u2014 specify 5356 when:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The base metal is a 5xxx alloy with more than 3% magnesium \u2014 5083, 5086, 5056, 5456 \u2014 and service stays below 65 \u00b0C.<\/li>\n\n\n\n<li>The joint sees saltwater or a marine atmosphere, and the weld zone must not become the corrosion site.<\/li>\n\n\n\n<li>The part will be anodized and the weld has to match the parent plate.<\/li>\n\n\n\n<li>As-welded strength or shear strength is a design driver and 4043 does not reach it.<\/li>\n\n\n\n<li>The process is MIG and feedability matters \u2014 5356 feeds more reliably than the softer silicon fillers.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No-go \u2014 do not use 5356 when:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The assembly runs continuously above 65 \u00b0C.

The cost of that magnesium is a hard service ceiling. Above roughly 65 \u00b0C the joint becomes susceptible to stress corrosion cracking, and the only fixes are a low-magnesium filler such as ER5554 or a change to a silicon filler. Work through the temperature question before the strength question, and the rest of the selection follows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We supply 5356 as MIG spool wire and TIG cut-length rod in the diameters and packaging your process needs, and we flag any job where ER5554 would be the safer filler.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Send the base alloy, section thickness, process and service temperature, and we will confirm the filler before you write the WPS.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Veelgestelde vragen<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Wat is het verschil tussen 5356- en 4043-vulmetaal?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">5356 is a 5% magnesium filler for 5xxx base metals. 4043 is a 5% silicon filler for 6xxx alloys and castings.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sterkte<\/strong> \u2014 5356 deposits roughly 50% more as-welded tensile.<\/li>\n\n\n\n<li><strong>Corrosie<\/strong> \u2014 5356 matches 5xxx parent metal, while 4043 does not.<\/li>\n\n\n\n<li><strong>Anodiseren<\/strong> \u2014 5356 stays light; 4043 darkens.<\/li>\n\n\n\n<li><strong>Flu\u00efditeit<\/strong> \u2014 4043 wets out better and cracks less on 6061.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">What is the maximum service temperature for 5356 welds?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Treat 65 \u00b0C (150 \u00b0F) as the standard ceiling for continuous service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Above 65 \u00b0C, alloys holding more than 3% magnesium \u2014 5356, 5183 and 5556 among them \u2014 sensitize and can crack under stress in salt water. For hot service specify ER5554, which stays under 3% magnesium.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is 5356 geschikt voor maritiem lassen?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. It is the standard filler for 5xxx marine work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">5083 and 5086 hulls, decks, tanks and superstructure rely on it because the magnesium match keeps weld-zone corrosion potential close to the parent plate. The one exception is warm service: above 65 \u00b0C, change to ER5554.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the minimum order for 5356 wire, and can you supply test certificates?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Low-MOQ production is available, and every order carries a mill test certificate.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Stock sizes<\/strong> \u2014 standard diameters ship from inventory.<\/li>\n\n\n\n<li><strong>Non-standard<\/strong> \u2014 custom diameters and spool weights run 10\u201360 days.<\/li>\n\n\n\n<li><strong>Documenten<\/strong> \u2014 MTC standard; SGS composition or mechanical reports on request.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>What Is 5356 Aluminum? 5356 is an aluminum-magnesium filler alloy.
