5086 aluminum<\/a> as plate and sheet in O, H111, H112, H32, H34, H116, and H321, and as bar in H111 and H112 \u2014 bar is not produced in the marine tempers, since H116 and H321 are flat-rolled specifications. In-house capability covers CNC machining, welding, laser cutting, and surface finishing; forging is coordinated through partner process facilities rather than run in-house, so allow for it in planning if your part needs it.<\/p>\n\n\n\nEvery shipment carries a mill test certificate (MTC), and SGS testing can be arranged on request. We do not issue classification-society certificates as standard \u2014 where DNV, ABS, LR, or CCS approval is required, confirm it with your yard early and we will work to the project’s approval path. For non-stock dimensions, typical lead time is 10\u201360 days, and we support low minimum order quantities on trial and prototype builds.<\/p>\n\n\n\n
Send your drawing or specification and we will confirm available tempers, sizes, tolerances, and documentation, and flag anything in the service conditions that points to a different alloy.<\/p>\n\n\n\n

5086 earns its place as the practical middle of the marine 5xxx range: more strength than 5052, more formability and weldability than 5083, and excellent seawater corrosion in the tempers that are tested for it. The three things that decide whether it is right for a job are the temper on the order, the 65 \u00b0C ceiling, and how the welded joint is designed around HAZ softening. Get those right and 5086 is a forgiving, well-documented alloy with decades of service behind it. Get them wrong \u2014 H32 specified for immersed service, sustained warm operation, or a weld sized on parent-metal strength \u2014 and the failure will look like a material problem when it was a specification problem.<\/p>\n\n\n\n
\u5e38\u89c1\u95ee\u9898<\/h2>\n\n\n\nIs 5086 stronger than 5083?<\/h3>\n\n\n\n
No. 5083 carries roughly 10\u201315% more tensile and yield strength because of its higher magnesium range (4.0\u20134.9% versus 3.5\u20134.5%). 5086 trades that margin for better formability, easier welding, and usually lower material cost. Where the design does not need 5083’s extra strength, 5086 is the more economical call.<\/p>\n\n\n\n
What is the 65 \u00b0C limit on 5086?<\/h3>\n\n\n\n
Sustained service above about 65 \u00b0C (150 \u00b0F) can cause magnesium to precipitate at grain boundaries as the beta phase (Al\u2083Mg\u2082), which is anodic to the surrounding metal and opens the alloy to intergranular corrosion, exfoliation, and stress corrosion cracking. The change is not reversible by heat treatment. H116 and H321 tempers are processed and tested to resist it, but the temperature ceiling still applies.<\/p>\n\n\n\n
Does 5086 lose strength when welded?<\/h3>\n\n\n\n
Yes, in the heat-affected zone. 5086 is non-heat-treatable, so the welding cycle anneals out the cold work locally and the HAZ reverts toward the O condition \u2014 an H32 assembly retains roughly 70\u201375% of parent yield strength across that band, with yield falling from ~210\u2013230 MPa toward ~115\u2013145 MPa. Welded structure should be sized on annealed HAZ properties per AWS D1.2, not on parent-temper values.<\/p>\n\n\n\n
Which filler wire should I use for 5086?<\/h3>\n\n\n\n
ER5183 is the usual first choice for welding 5086 to itself, giving the closest strength match to the base metal with good marine corrosion behavior. ER5356 is the general-purpose alternative and is slightly lower in as-welded strength. ER5556 is specified where joint strength governs and a higher-magnesium filler is acceptable.<\/p>\n\n\n\n
Is 5086 suitable for pressure vessels?<\/h3>\n\n\n\n
Yes. 5086 is a standard material for unfired welded pressure vessels under ASME Section VIII, supplied to ASME SB-209, and it is widely used for road tankers and chemical storage tanks. It has no ductile-to-brittle transition, so it also performs well at low temperatures. 5083 is preferred where higher allowable stress permits a thinner wall.<\/p>\n\n\n\n
Can 5086 be anodized?<\/h3>\n\n\n\n
Yes, but for protection rather than appearance. It anodizes to a harder, more corrosion-resistant surface, but the high magnesium content makes the finish less bright and uniform than 5005 or 6063, and color consistency across batches is harder to hold. For decorative anodized parts, specify 5005 or 6063 instead.<\/p>","protected":false},"excerpt":{"rendered":"
What 5086 Aluminum Is 5086 belongs to the aluminum\u2013magnesium family. Magnesium is the primary alloying element and the source of both its solid-solution strength and its seawater performance; manganese and chromium are deliberate additions that control grain structure and limit intergranular attack. Copper is held to 0.10% maximum because even small amounts degrade chloride corrosion […]<\/p>\n","protected":false},"author":1,"featured_media":10576,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"5056 Aluminum: Properties, Tempers & Applications","_seopress_titles_desc":"A practical guide to 5056 aluminum: composition, O\/H32\/H34\/H38 tempers, mechanical properties, welding and forming notes, plus where rivet wire fits best.","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"","footnotes":""},"categories":[177],"tags":[],"class_list":["post-8412","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-5000_6000-series-aluminum"],"_links":{"self":[{"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/posts\/8412","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/comments?post=8412"}],"version-history":[{"count":3,"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/posts\/8412\/revisions"}],"predecessor-version":[{"id":10581,"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/posts\/8412\/revisions\/10581"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/media\/10576"}],"wp:attachment":[{"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/media?parent=8412"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/categories?post=8412"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/premiumalu.com\/zh\/wp-json\/wp\/v2\/tags?post=8412"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
