Cast aluminu-silicon alloys
Category:Aluminum alloy casting
Cast aluminu-silicon alloys is a process in which aluminum-silicon alloys are processed into products that can be directly used through a casting process. Common grades are A356.0, A413.0 and so on.
Cast aluminu-silicon alloys is a very important industrial alloy. It has important uses in the automobile manufacturing industry, high-tech electronics industry, aerospace materials and other products, and is an ideal wear-resistant material.
Aluminum silicon alloy may be a reasonably ferroalloy with aluminum and silicon because the main components. Generally, the content of silicon is 11%, and atiny low amount of copper, iron and nickel are added to enhance the strength.Aluminum silicon alloy is employed to manufacture low and medium strength castings with complex shapes, like covering, motor shell, bracket, etc. it's also used as brazing solder.
When the silicon content is low (such as 0.7), the ductility of aluminum silicon alloy is sweet, which is usually used as deformation alloy.
When the silicon content is high (such as 7%), the filling property of aluminum silicon alloy melt is nice, which is usually used as casting alloy.
In the Al Si alloy with silicon content exceeding Al Si eutectic point (silicon 12.6%), when the particle content of silicon is as high as 14.5% ~ 25%, adding a specific amount of Ni, Cu, Mg and other elements can improve its comprehensive mechanical properties.
