Aluminum Silicon Carbide Structural Parts Description

Aluminum Silicon Carbide is a metal-ceramic composite material consisting of silicon carbide particles dispersed in a matrix of aluminum alloy.  It combines the benefits of high thermal conductivity of metal and low coefficient of thermal expansion of ceramic. Aluminum Silicon Carbide Structural Parts were first used in the US military radar chip substrate to replace tungsten copper. After the replacement, the heat dissipation effect is excellent, and the overall weight loss of the radar is 10 kg, which makes the aluminum-silicon carbide material attract attention.
