6082 aluminium alloy
6082 aluminium alloy is an alloy in the wrought aluminium–magnesium–silicon family. It is one of the more popular alloys in its series, although it is not strongly featured in ASTM standards. It is typically formed by extrusion, cold and hot stamping, 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.
Alternate names and designations include AlSi1MgMn, 3.2315, H30, and A96082. The alloy and its various tempers are covered by the following standards:
- EN 485-2: Aluminium and aluminium alloys. Sheet, strip and plate. Mechanical properties
- EN 573-3: Aluminium and aluminium alloys. Chemical composition and form of wrought products. Chemical composition and form of products
- EN 754-2: Aluminium and aluminium alloys. Cold drawn rod/bar and tube. Mechanical properties
- EN 755-2: Aluminium and aluminium alloys. Extruded rod/bar, tube and profiles. Mechanical properties
- ISO 6361: Wrought Aluminium and Aluminium Alloy Sheets, Strips and Plates
