The main alloying elements of 6061 aluminum rod are magnesium and silicon, forming a Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the harmful effects 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 also a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on conductivity; Zirconium or titanium can refine grain size and control recrystallization structure; To improve machinability, lead and bismuth can be added.
