L'\u00e9tirage est ce qui am\u00e9liore la stabilit\u00e9 dimensionnelle pendant et apr\u00e8s l'usinage, donc le T651 est la d\u00e9signation pour la plaque qui sera fortement usin\u00e9e. La t\u00f4le est normalement fournie en T6 plut\u00f4t qu'en T651, car l'\u00e9tape d'\u00e9tirage est une op\u00e9ration pour plaque et barre.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">La voie forme-puis-vieillissement<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">C'est la raison pour laquelle de nombreux ateliers sp\u00e9cifient le 6013 tout court, et c'est le point que la plupart des fiches techniques omettent. Le vieillissement naturel en T4 progresse lentement, donc une pi\u00e8ce peut \u00eatre form\u00e9e en T4 puis vieillie directement jusqu'\u00e0 la r\u00e9sistance maximale T6 <strong>sans une seconde mise en solution<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00c0 titre de comparaison, le 2024-W doit \u00eatre r\u00e9frig\u00e9r\u00e9 pour maintenir sa formabilit\u00e9, et la plupart des pi\u00e8ces 6xxx qui sont form\u00e9es puis vieillies n\u00e9cessitent d'abord une remise en solution. Sauter cette retrempe sur le 6013 signifie moins de distorsion \u00e0 corriger, moins d'\u00e9tapes de processus et aucun re-contr\u00f4le de la structure granulaire. Si votre pi\u00e8ce est grande, fine ou sensible \u00e0 la distorsion, cette voie seule peut justifier le surco\u00fbt de l'alliage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Travailler avec le 6013<\/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\/Working-With-6013-Corrosion-Limits.png\" alt=\"\" class=\"wp-image-10627\" srcset=\"https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-6013-Corrosion-Limits.png 800w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-6013-Corrosion-Limits-300x225.png 300w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-6013-Corrosion-Limits-768x576.png 768w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-6013-Corrosion-Limits-16x12.png 16w, https:\/\/premiumalu.com\/wp-content\/uploads\/2025\/05\/Working-With-6013-Corrosion-Limits-600x450.png 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Formation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Effectuez le formage en T4. En T6, l'alliage a une capacit\u00e9 de pliage limit\u00e9e et le formage \u00e0 froid est restreint par le niveau de r\u00e9sistance ; les formes complexes qui se forment facilement en T4 fissureront en T6.

Les donn\u00e9es des producteurs d'aluminium classent sa soudabilit\u00e9 au sommet de l'\u00e9chelle et le d\u00e9crivent comme facilement assembl\u00e9 par les m\u00e9thodes conventionnelles de soudage et de brasage \u2014 c'est l'un des principaux avantages de cet alliage sur le 2024, qui n'est pas consid\u00e9r\u00e9 comme soudable par fusion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La mise en garde habituelle s'applique toujours : une soudure 6xxx perd de la r\u00e9sistance localement parce que la chaleur du soudage survieillit ou remet en solution la structure de pr\u00e9cipit\u00e9s dans et pr\u00e8s de la zone de soudure. Concevez pour l'\u00e9tat brut de soudage et placez les soudures loin des zones de contrainte maximale lorsque c'est possible. La s\u00e9lection du m\u00e9tal d'apport doit suivre les exigences du joint et toute qualification de mode op\u00e9ratoire applicable \u2014 voir notre <a href=\"https:\/\/premiumalu.com\/fr\/conseils-dexperts-sur-le-fil-a-souder-en-aluminium-pour-reussir\/\">guide de s\u00e9lection des fils de soudage pour l'aluminium<\/a> pour comprendre comment le choix du m\u00e9tal d'apport interagit avec l'alliage de base et l'environnement de service.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Usinage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">L'usinabilit\u00e9 est bonne, \u00e9valu\u00e9e \u00e0 environ 70 sur l'\u00e9chelle standard de 0 \u00e0 100 o\u00f9 les alliages \u00e0 usinage rapide se situent pr\u00e8s de 90. Le T651 est g\u00e9n\u00e9ralement pr\u00e9f\u00e9r\u00e9 pour la plaque fortement usin\u00e9e en raison de la relaxation des contraintes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Traitement de surface<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Le 6013 prend bien l'anodisation et la peinture. Ce n'est pas un alliage d\u00e9coratif pour anodisation brillante \u2014 si des garnitures brillantes \u00e0 apparence critique sont requises, le 5005, le 5657 ou le 6063 sont les r\u00e9ponses standard. Pour l'anodisation protectrice et le pr\u00e9traitement de peinture, le 6013 performe sans manipulation sp\u00e9ciale.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Limites de corrosion et de temp\u00e9rature<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le cadrage honn\u00eate est le suivant : le 6013 a une <strong>bonne<\/strong> r\u00e9sistance \u00e0 la corrosion pour un alliage contenant du cuivre, et <strong>moins<\/strong> general corrosion resistance than 6061. Published comparisons note a higher tendency toward intergranular corrosion in 6013 than in 6061, particularly where processing is not properly controlled \u2014 with reported knock-on effects on fatigue resistance, ductility and strength if it is left unchecked.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stress-corrosion cracking resistance is rated at the top of the producer scale, which is a genuine improvement over the 2xxx alloys 6013 competes with. But 6013 is not a marine alloy.

Choose 6013 when the strength margin is what fails the design, not as a default upgrade. If corrosion resistance is the priority, 6061 is the better answer \u2014 see our <a href=\"https:\/\/premiumalu.com\/fr\/guide-complet-de-laluminium-6061\/\">complete guide to 6061 aluminium<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>6013 vs 2024.<\/strong> Strength, fracture toughness and fatigue in 6013-T6 land close to 2024-T3 plate, with better corrosion resistance and lower density. The deciding factor is usually joining: if the assembly is welded, 6013 wins; if it is riveted and corrosion is managed by cladding or finishing, 2024 may still be specified.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Go \/ No-Go<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Go \u2014 specify 6013 when:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A welded joint is required in a part that needs strength beyond 6061. Typical parts: welded aerospace assemblies, hydraulic manifolds, structural brackets.<\/li>\n\n\n\n<li>The part can be formed in T4 and aged directly to T6, avoiding a re-solution treatment. Typical parts: large distortion-sensitive panels, drawn structural shapes.<\/li>\n\n\n\n<li>Fatigue resistance is a design driver and T6&#8217;s ~140 MPa fatigue strength clears the duty cycle. Typical parts: dynamically loaded brackets, transport structures.<\/li>\n\n\n\n<li>2024-T3-class properties are needed but the service environment rules out a bare 2xxx alloy.<\/li>\n\n\n\n<li>Heavily machined plate where dimensional stability matters \u2014 specify T651.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No-Go \u2014 cherchez ailleurs lorsque :<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Maximum corrosion resistance is the priority. 6061 or a 5xxx alloy will outperform 6013; the copper content works against you.<\/li>\n\n\n\n<li>The part sees continuous service above roughly 160 \u00b0C.<\/li>\n\n\n\n<li>Immersed or splash-zone saltwater is the primary exposure.

Form in T4 and age, or pick a more formable alloy.<\/li>\n\n\n\n<li>Availability and cost dominate. 6061 is stocked far more widely and is the safer default.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Sourcing Checks<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">6013 is not a commodity grade, so the order needs more definition than a 6061 line item. Before releasing a purchase order, confirm:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Specification and temper together<\/strong> \u2014 ASTM B209 or the applicable AMS sheet callout (4216 for T6, 4347 for T4), plus the temper. 6013-T6 and 6013-T651 are not interchangeable on a drawing.<\/li>\n\n\n\n<li><strong>Thickness band<\/strong> \u2014 guaranteed mechanical minimums vary with thickness. State the range you will accept.<\/li>\n\n\n\n<li><strong>Heat treatment route<\/strong> \u2014 if you intend to form in T4 and age to T6, say so at order stage so the material is supplied in a condition that supports it.<\/li>\n\n\n\n<li><strong>MTC scope<\/strong> \u2014 request the certificate with chemistry and mechanical results, and confirm the temper and specification appear on it.<\/li>\n\n\n\n<li><strong>Tests par tierce partie<\/strong> \u2014 where the application is aerospace or pressurised, agree the additional test scope up front rather than after production.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Linsy Aluminium supplies 6013 in sheet and plate, and supports CNC machining, TIG and MIG welding, laser cutting and surface finishing in-house, so material and first-stage processing can be handled on one order. See the <a href=\"https:\/\/premiumalu.com\/fr\/produit\/alliage-daluminium-6013\/\">6013 aluminium alloy<\/a> product page for available tempers and dimensions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">6013 earns its place when a welded, fatigue-loaded part needs more strength than 6061 carries, and when forming in T4 and ageing straight to T6 \u2014 no re-solution treatment, no extra quench \u2014 is worth the premium. The trade-off is availability: copper raises the intergranular corrosion tendency above 6061, the grade costs more, and most mills hold far less of it than 6061 or 2024.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We supply 6013 sheet and plate to the standard specifications and run low-MOQ custom production for tempers and dimensions outside them, with a 10\u201360 day lead time on custom lines. Every order ships with an MTC.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/premiumalu.com\/fr\/contact\/\" data-type=\"link\" data-id=\"https:\/\/premiumalu.com\/contact\/\">Envoyez-nous le plan<\/a>, temper and thickness requirement for a technical review and quotation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Questions fr\u00e9quemment pos\u00e9es<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What forms does 6013 come in?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sheet, plate and coil are the rolled forms. Tube, bar and non-standard sections are produced to your drawing, so the grade is not limited to flat product. Name the temper alongside the form, because not every temper runs in every product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What filler should I use to weld 6013?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ER4043 (AlSi5) or ER5356 (AlMg5Cr) to AWS A5.10. ER4043 is the usual first choice on 6xxx base metal because its higher silicon content lowers hot-cracking sensitivity. Move to ER5356 where the joint needs a stronger as-welded deposit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How does 6013 compare with 6061 on cost and availability?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It costs more and is stocked far less widely. 6061 is a commodity grade held by most service centres, while 6013 is a niche aerospace alloy, so lead time depends on whether your temper and thickness are held or produced. Budget for the premium and confirm stock before you commit to a delivery date.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can 6013 be cut or machined to drawing before shipment?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Cutting to length, CNC machining, laser cutting and bending are handled in-house, so parts can arrive close to finished size. Send the drawing with your enquiry and the tolerance and surface callouts are quoted alongside the material.<\/p>","protected":false},"excerpt":{"rendered":"<p>6013 exists for one design problem: a part that needs 2024-T3-class strength but has to be welded. 6061 will weld, but it runs out of strength just above 310 MPa in T6. 2024-T3 has the strength, but it is not a fusion-welding alloy and needs cladding or paint to survive service. 6013 closes that problem [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":10624,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"6013 Aluminum: Properties, Tempers, and When to Specify","_seopress_titles_desc":"Specifying 6013 aluminum?
