The key alloying elements of aluminum alloy rod are magnesium and silicon, and Mg2Si is produced. If there is a certain amount of manganese and chromium, can be combined with iron bad effect; Sometimes a small amount of copper or zinc is added to improve the alloy's compressive strength without significantly reducing its corrosion resistance; There is also a small amount of copper in the conductive raw materials to offset the negative effects of titanium and iron on the conductivity; Zirconium or titanium can optimize crystals and manipulate work hardening mechanisms; To improve drillability, lead and bismuth can be added. In Mg2Si solid solution aluminum, the alloy has artificial aging hardening. The key alloy elements in the aluminum alloy rod are magnesium and silicon, which have medium compressive strength, excellent corrosion resistance, electric weldability, and good effect of air oxidation.

Aluminum alloy rod is a high quality aluminum alloy commodity produced by heat treatment process and pre-Lashen processing technology. Aluminum alloy rod has excellent production and processing performance, good electric welding characteristics and electroplating technology, excellent corrosion resistance, high ductility and no deformation after production and processing, high density of raw materials without defects and easy polishing, coloring film is very easy, air oxidation effect is excellent and other good characteristics.
