6082 Aluminum Alloy Plate
6082 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the more popular alloys in its series (alongside alloys 6005, 6061, and 6063), although it is not strongly featured in ASTM (North American) standards. It is typically formed by extrusion and rolling, but as a wrought alloy it is not used in casting. It can also be forged and clad, but that is not common practice with this alloy. It cannot be work hardened, but is commonly heat treated to produce tempers with a higher strength but lower ductility.
6082 aluminum alloy is a medium strength alloy with excellent corrosion resistance. 6082 aluminum alloy has the highest strength of the 6000 series alloy. Due to the higher strength of 6082 aluminum alloy it has replaced Alloy 6061 in many applications. 6082 aluminum alloy is typically used in highly stressed applications, Trusses, Bridges, Cranes, Transport applications, Ore Skips, Beer Barrels, Milk churns.
Alternate names and designations include AlSi1MgMn, 3.2315, H30, and A96082. The alloy and its various tempers are covered by the following standards:

Temper Types:
- F - As fabricated.
- T5 - Cooled from an elevated temperature shaping process and artificially aged. Applies to products that are not cold worked after cooling.
- T5511 - Cooled from an elevated temperature shaping process, stress relieved by stretching and artificially aged.
- T6 - Solution heat treated and artificially aged.
- O - Annealed. This is the lowest strength, highest ductility temper.
- T4 - Solution heat treated and naturally aged to a substantially stable condition. Applies to products that are not cold worked after solution heat-treatment.
- T6511 - Solution heat treated, stress relieved by stretching, and artificially aged.
Applications:
