The Classification of the AlSi Alloys

As a important industry material, the AlSi alloys can be classified into four kinds:

1.Hypo eutectic silicon aluminum alloys contents 9%-12% silicon content.

2.Eutectic AlSi alloys contents 11%-13% silicon content.

3.Hypereutectic silicon aluminum alloys has over 12% silicon content, which are main 15%~20%.

4.The silicon content above 22% is called high silicon aluminum alloys, which can up to the 80%.
