5182 \uc54c\ub8e8\ubbf8\ub284<\/a> as sheet and coil in O, H111, H32, H34, and H19, with H116 and H321 available for marine-oriented supply \u2014 as with other high-magnesium grades, the marine tempers are flat-rolled specifications and are not produced in bar. 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. For automotive panel or can stock work, tell us which properties govern \u2014 r-value, n-value, or coil consistency \u2014 so the inquiry goes to the mill with the right window attached. 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, gauges, tolerances, and documentation, and flag anything in the service conditions that points to a different alloy.<\/p>\n\n\n\n

5182 is the strongest of the commonly supplied formable 5xxx alloys, and it holds two markets that pull it in opposite directions: H19 can stock at very high strength and low elongation, and automotive sheet in O through H34 chosen for how far it draws. Pick the temper first, because the spread across tempers is wider than the difference between many alloys. Respect the 65 \u00b0C ceiling, since 4.0\u20135.0% magnesium leaves less margin than most grades. And design welded joints on annealed HAZ properties rather than parent-temper values. Get those three right and 5182 is a capable, well-documented alloy with deep supply behind it. Get them wrong \u2014 H19 specified for a deep draw, warm continuous service, or a weld sized on H34 strength \u2014 and the failure will look like a material problem when it was a specification problem.<\/p>\n\n\n\n
\uc790\uc8fc \ubb3b\ub294 \uc9c8\ubb38<\/h2>\n\n\n\nWhat is 5182 aluminum mainly used for?<\/h3>\n\n\n\n
Two dominant applications. The largest globally is can end stock<\/strong> \u2014 beverage can ends, easy-open ends, and pull tabs \u2014 supplied in the H19 temper. The second is automotive body panels<\/strong> such as hoods, doors, fenders, and inner panels, in O through H34. Note that can bodies<\/em> are usually a 3xxx alloy such as 3004; 5182 is the end<\/em> \uadf8\ub9ac\uace0 tab<\/em> material.<\/p>\n\n\n\nHow strong is 5182 aluminum?<\/h3>\n\n\n\n
It depends entirely on temper, and the spread is wide: roughly 276 MPa tensile \/ 145 MPa yield \/ 21% elongation in O, versus about 420 MPa tensile \/ 395 MPa yield \/ 4% elongation in H19. Automotive body panel tempers sit in between \u2014 H32 around 290\u2013315 MPa tensile and 210\u2013230 MPa yield, H34 around 331 MPa and 255 MPa.<\/p>\n\n\n\n
Is 5182 stronger than 5052?<\/h3>\n\n\n\n
Yes, meaningfully. 5182-H34 reaches about 331 MPa tensile against roughly 210\u2013260 MPa for 5052-H32, with correspondingly higher yield. The trade-off is formability and cost: 5052 draws further in deep-draw work, welds a little more easily, and is usually cheaper. Choose 5182 when strength or dent resistance governs; choose 5052 when maximum drawability or cost governs.<\/p>\n\n\n\n
Can 5182 aluminum be welded?<\/h3>\n\n\n\n
Yes, by MIG and TIG, typically with ER5356 filler, or ER5183 where higher as-welded strength is needed. The important caveat is that 5182 is non-heat-treatable, so the heat-affected zone is annealed by welding and cannot be restored \u2014 welded joints are weaker than H-temper parent metal, and joints should be sized on annealed HAZ properties per AWS D1.2.<\/p>\n\n\n\n
What is the maximum service temperature for 5182?<\/h3>\n\n\n\n
About 65 \u00b0C (150 \u00b0F)<\/strong> for continuous service in corrosive environments. Above that, the 4.0\u20135.0% magnesium content can precipitate at grain boundaries as the beta phase, leading to intergranular corrosion and stress corrosion cracking. The change is not reversible by heat treatment, so for warm sustained service specify 5052 or 5454 instead.<\/p>\n\n\n\nIs 5182 good for deep drawing?<\/h3>\n\n\n\n
In the soft tempers, yes. 5182-O and H111 offer around 18\u201321% elongation and draw well for automotive inner panels, tank ends, and stamped shells. It does not draw quite as far as 5052, and it work-hardens faster, so expect more force, larger bend radii, and possibly interstage annealing on multi-step draws. For exposed automotive panels, specify r-value and n-value, not just elongation.<\/p>\n\n\n\n
What is the difference between 5182-H19 and 5182-H32?<\/h3>\n\n\n\n
They are at opposite ends of the temper range and are not interchangeable. H19<\/strong> is heavily cold-rolled to maximum strength \u2014 about 420 MPa tensile, 395 MPa yield, only 4% elongation \u2014 and is used for can ends and pull tabs, where the operation is punching and scoring rather than drawing. H32<\/strong> is strain-hardened and stabilized to about 290\u2013315 MPa tensile and 210\u2013230 MPa yield with 10\u201312% elongation, and is used for automotive body panels and structural sheet.<\/p>","protected":false},"excerpt":{"rendered":"What 5182 Aluminum Is 5182 is an aluminum\u2013magnesium alloy strengthened by solid-solution magnesium and by cold work.
