What is the composition of aluminum alloy?

Aluminum alloy is an alloy composed of many elements, including silicon, iron, copper, manganese, magnesium, chromium, zinc and titanium.

Aluminum and aluminum alloys can be melted in various ways. Coreless induction furnaces and trough induction furnaces, crucible furnaces and reflective open hearth furnaces (burning natural gas or fuel oil), resistance furnaces and electrothermal radiation furnaces are usually used.

There are many kinds of burden, from high-quality prealloyed ingots to ingots specially composed of low-grade wastes.

606 1 aluminum alloy element

The main alloying elements of 606 1 aluminum alloy are magnesium and silicon, forming Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the adverse 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 the grain and control the recrystallization structure; In order to improve machinability, lead and bismuth can be added.

When Mg2Si is dissolved in aluminum, the alloy has the effect of artificial age hardening. The main alloying elements in 606 1 aluminum alloy are magnesium and silicon, which have moderate strength, good corrosion resistance and weldability, and good oxidation effect.
