Definition of 6061 aluminum alloy

6061 aluminum alloy is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process.
6061 aluminum is a heat-strengthened alloy with good formability, weldability, machinability, and medium strength. It can still maintain good operability after annealing. The main alloying elements of 6061 aluminum are Magnesium and silicon form the Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing its corrosion resistance; there is a small amount of conductive materials In order to offset the adverse effects of titanium and iron on conductivity; zirconium or titanium can refine the grain and control the recrystallization structure; in order to improve the machinability, lead and bismuth can be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial age hardening function.
