product description

6061 aluminum block is a heat-treated reinforced alloy, which has good formability, weldability, machinability, and at the same time has medium strength, and can maintain good operability after annealing. The main alloying elements of 6061 aluminum block are Magnesium and silicon, and 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 improve the strength of the alloy without ficantly reducing its corrosion resistance; there is still a small amount of conductive material. copper to offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization; in order to improve machinability, lead and bismuth can be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial aging hardening function.
