Het kenmerkende aspect is de vrijsnijdende toevoeging: bismut bij 0,50\u20131,50% breekt de spaander, terwijl lood is begrensd op 0,40% in plaats van het mechanisme te zijn. Dat behoudt de corrosieweerstand en het anodiseergedrag van een gewone 6xxx terwijl de spaanderbeheersing van een vrijsnijdende kwaliteit wordt toegevoegd \u2014 de rol die 6262 en 6012 vervulden, met bismut dat de spaander breekt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De afweging zit in waar de legering staat, niet in wat hij kan. Bismut verhoogt de sterkte niet, dus 6026 is in de eerste plaats een bewerkingskwaliteit en in de tweede plaats een constructiekwaliteit; waar maximale sterkte de drijfveer is, doen 6082 of 7075 dat werk beter. Wat in de praktijk een 6026-onderdeel bepaalt, is de temper, omdat de spreiding over T6, T8, T9 en T6510\/T6511 loopt van 300 tot 330 MPa in rekgrens en van 8% tot 4% in rek \u2014 breed genoeg om te bepalen of het onderdeel \u00fcberhaupt kan worden gevormd.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Chemische samenstelling (EN 573-3)<\/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\/How-the-T-Tempers-Are-Produced.webp\" alt=\"Hoe de T-tempers worden geproduceerd\" class=\"wp-image-10794\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/How-the-T-Tempers-Are-Produced.webp 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/How-the-T-Tempers-Are-Produced-300x225.webp 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/How-the-T-Tempers-Are-Produced-768x576.webp 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/How-the-T-Tempers-Are-Produced-16x12.webp 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/How-the-T-Tempers-Are-Produced-600x450.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Bismut is de bewuste toevoeging; tin en lood zitten op onzuiverheidsplafonds.

Het achtervoegsel na T registreert wat er rond die kernsequentie gebeurt \u2014 en de volgorde van koudvervorming ten opzichte van veroudering is wat T8 van T9 scheidt.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>T6<\/strong> \u2014 oplossingsgegloeid, vervolgens kunstmatig verouderd.

Veroudering heeft het precipitaat al gevormd; het koudtrekken voegt daar dislocatieversterking aan toe en legt de diameter in dezelfde doorgang vast. Een T9-staf arriveert met zijn afmetingen en zijn restspanning al vastgelegd, wat de reden is dat precisagedraaide onderdelen gewoonlijk in T9 worden gespecificeerd \u2014 de diameter die u bewerkt is de diameter die de staf aanhoudt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">T8 keert die volgorde om. Koudvervorming gaat erin v\u00f3\u00f3r veroudering, dus de staf wordt op zijn getrokken maat verouderd in plaats van na veroudering getrokken. Een T8-staf bereikt 315 MPa rekgrens en 345 MPa treksterkte bij 4% rek \u2014 meer rekgrens dan T6, 15 MPa minder dan T9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6026-T9 in cijfers<\/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\/Machining-Anodizing-and-Welding.webp\" alt=\"Machining, Anodizing and Welding\" class=\"wp-image-10796\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/Machining-Anodizing-and-Welding.webp 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/Machining-Anodizing-and-Welding-300x225.webp 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/Machining-Anodizing-and-Welding-768x576.webp 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/Machining-Anodizing-and-Welding-16x12.webp 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2026\/11\/Machining-Anodizing-and-Welding-600x450.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">De onderstaande minimumwaarden zijn afkomstig uit EN 754-2 voor koudgetrokken staf en EN 755-2 voor ge\u00ebxtrudeerd product.

The 330 MPa proof stress is the highest the alloy offers, and the cold-finished diameter means the bar is already where the tolerance wants it. The cost is 4% elongation: T9 leaves almost no room for a bend, a swage, or a crimp after delivery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>T6<\/strong> covers the widest range of work. Its 370 MPa tensile and 8% elongation give room to form or straighten after heat treatment, and it is the temper extruded tube and profile come in. If the part needs any deformation after aging, T6 or one of its stress-relieved versions is the one that can still take it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>T8<\/strong> sits between them and is easy to overlook. It is a drawn-bar temper like T9, but with cold work ahead of aging: 315 MPa proof stress and 345 MPa tensile, still at 4% elongation. Specify T8 when the drawing calls for more proof stress than T6 and the part will not be formed \u2014 but T9 is available, it gives 15 MPa more proof stress at the same elongation, so T8 usually loses that comparison on a like-for-like drawing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>T6510 and T6511<\/strong> are the stress-relieved versions of T6 and exist only for extruded product. They change residual stress, not the strength line, so the choice between them and T6 is about distortion after machining rather than load capacity. T6510 forbids straightening after the stretch; T6511 allows light straightening to hold tolerance, which is why it appears more often on standard extruded sections.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Shapes and Sizes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The temper usually decides the form. T9 and T8 are drawn-bar tempers; T6510 and T6511 are extruded; T6 exists in both. Where a drawing needs a temper the standard form does not carry, the route changes \u2014 the order does not get refused.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bar and rod<\/strong> \u2014 round 6\u2013400 mm, hex and square 6\u2013200 mm, length 1000\u20136000 mm.

The bismuth chip control is what pays for the alloy, and it pays most on automatic lathes running long batches.<\/li>\n\n\n\n<li><strong>Go<\/strong> when the part needs an anodized finish and free-machining behavior at the same time; a leaded free-machining grade dulls that finish and carries its own compliance burden. Note the qualification: 6026 meets ELV and RoHS <strong>under the lead exemption for aluminum alloys<\/strong>, which permits up to 0.40% Pb.

T6, T8 and T6510\/T6511 trade that yield back for formability or for lower residual stress in large sections.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We draw and supply 6026 in T6, T8, T9, T6510 and T6511 across bar, sheet, tube and custom profiles, with MTC on every order and coil quoted on enquiry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Send your drawing with the standard, temper and size band, and we will confirm the production route and lead time 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\">What is 6026 T9 aluminum?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">6026 is a low-lead free-machining 6xxx alloy, and T9 is the temper produced by aging the bar and then cold working it. Because the cold draw is the last step, the bar arrives strengthened and dimensionally finished \u2014 which is why T9 suits precision turned parts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is 6026 T9 stronger than T6?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It depends which strength you mean. T9 reaches a higher 0.2% proof stress, 330 MPa against T6&#8217;s 300, so it resists permanent set better. Its tensile minimum is 360 MPa against T6&#8217;s 370 \u2014 10 MPa lower \u2014 and its elongation drops from 8% to 4%.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can 6026 T9 be welded?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, by TIG or MIG, but the joint will not hold T9 properties. The heat-affected zone reverts toward the annealed condition, and no post-weld aging treatment restores the T9 structure in this grade. If the finished assembly must carry T9 strength across a weld, change the design to a mechanical joint or pick a temper you can accept losing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which tempers do you supply, and what is the minimum order?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">We supply bar, sheet, tube and custom profiles in T6, T8, T9, T6510 and T6511. Coil is quoted on enquiry. Round bar runs 6\u2013400 mm and sheet 0.5\u2013120 mm thick.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Non-standard sizes go to low-MOQ custom production, typically 10\u201360 days.
