    Silicon carbide aluminum matrix composites have excellent performance and have many outstanding advantages: low density, high specific stiffness, low coefficient of thermal expansion, high thermal conductivity, etc., which are very suitable for high stability optical machine systems. For example: (1) high structural stability (static stiffness, dynamic stiffness): the elastic modulus is 2 times that of titanium alloy, 3 times that of aluminum alloy, and the specific stiffness is 3 times that of aluminum alloy and titanium alloy; (2) high thermal control stability: the coefficient of thermal expansion can be 20% lower than that of titanium alloy, and the thermal conductivity is 30 times that of titanium alloy. Therefore, silicon carbide aluminum matrix composites have become an ideal material to replace other alloys.
