2024 3003 6061 T6 Aluminium Tube 2 Round Aluminum Tubing Pipe Square ASTM

​6061 aluminum is a heat-treatable alloy with good formability, weldability, machinability, and moderate strength, which can still maintain good operation after annealing. The main alloying elements of 6061 aluminum are magnesium and silicon, which form Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; Sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance; There is a small amount of copper in the conductive material to offset the bad effect of titanium and iron on the conductivity; Zirconium or titanium can refine grain and control recrystallization structure; Lead and bismuth can be added to improve machinability. Mg2Si is solidly dissolved in aluminum, and the alloy has the function of artificial aging hardening.
