High-silicon aluminum

Weden Metal Co.,Limited | Updated: Jan 12, 2018

Silicon aluminum alloy is very important in industry can be divided into four categories:

(1) hypoeutectic silicon aluminum alloy which contains 9% to 12% of silicon.

(2) eutectic silicon aluminum alloy containing 11% ~ 13% silicon.

(3) Hypereutectic silicon aluminum silicon content of 12% or more, mainly in the range of 15% to 20%.

(4) silicon content of more than 22%, known as high silicon aluminum alloy, which is mainly 25% -70%, the international silicon content

Up to 80%.


High-silicon aluminum alloy parts in the application

High silicon aluminum alloy (silicon content of 20% -35%) has excellent tribological properties, can be used as advanced lightweight wear-resistant materials, in all types of transport and various types of power machinery, machine tools, special fasteners And tools have been widely used. 

High silicon aluminum alloy with a small proportion, light weight, good thermal conductivity, low thermal expansion coefficient, volume stability and wear resistance, corrosion resistance and a series of advantages, but widely used as a cylinder engine, piston, rotor , Brake disc and other materials.
