Audited Supplier 6061 aluminum is a 6000-series aluminum alloy: there is significant alloying with both magnesium and silicon, and the alloy is formulated for primary forming into wrought products. 6061 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6061. AlMg1SiCu is the EN chemical designation. H20 is the British Standard (BS) designation. A96061 is the UNS number. Additionally, the AFNOR (French) designation is A-G1SUC. Older literature may refer to this material as CSA GS11N, but this is now discouraged.
It has been in use since 1935, but has only received its standard designation in 1954. This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.
Aluminum 6061 is one of the most versatile of the heat treatable alloy group. Alloy 6061 has good corrosion resistance and good weldability.
Aluminum 6061 is probably the most commonly available, heat treatable aluminum alloy.

Aluminium / Aluminum 6061 alloy can be easily formed and worked in the annealed condition. The standard methods are used to perform bending, stamping, deep drawing, and spinning operations.
Aluminium / Aluminum 6061 alloy has excellent weldability. Thinner sections can be welded using gas tungsten arc welding technique. Heavier sections can be welded using gas metal arc welding technique. Alloy 4043 filler wire can be used to achieve good result, but it will affect T 6 properties.
Aluminium / Aluminum 6061 alloy is heat treated at 533°C (990°F) for a sufficient period of time followed by quenching in water. Precipitation hardening process can be performed at 160°C (320°F) for 18 h followed by air cooling. This process is again repeated at 177°C (350°F) for 8 h followed by cooling in air.
Aluminium / Aluminum 6061 alloy is forged at 233 to 483°C (750 to 900°F).
Aluminium / Aluminum 6061 alloy is hot worked at 260 to 372°C (500 to 700°F).
Aluminium / Aluminum 6061 alloy is cold worked in the O temper condition. It can also be cold formed in the T 4 and T 6 tempers.
Annealing of Aluminium / Aluminum 6061 alloy can be performed at 775°F for 2 to 3 h followed by controlled cooling at 10 to 260°C (50 to 500°F) per hour, and air cooling.
Aging of Aluminium / Aluminum 6061 alloy can be performed at 177°C (350°F) for 8 h. It is then cooled in air.
