Silicon metal is widely used in the manufacturing process of aluminum alloyThe classification of metal silicon is usually classified according to the content of three main impurities of iron, aluminum and calcium contained in the metal silicon component. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 2202, 1101 and other different grades. When smelting aluminum alloy, it is usually necessary to wait for the aluminum ingot to dissolve before adding a certain percentage of silicon metal. High-quality silicon metal can effectively improve the mechanical properties of aluminum alloy and increase the yield.

The role of metal silicon in casting aluminum alloys is:

1. Improve the high temperature fluidity of the alloy;
2. Reduce shrinkage;
3. Reduce the tendency of thermal cracking;
4. Improve wear resistance

Of course, it is not that the more silicon content, the better. When the silicon content of the cast aluminum alloy exceeds 14%, silicon and aluminum form a hypereutectic. Difficult to process.High silicon cast aluminum alloys will seriously corrode the crucible.
