Aluminum based silicon carbide heat sink

Aluminum based silicon carbide (AlSiC) heat sink is a high-performance composite material heat dissipation solution composed of an aluminum alloy matrix and silicon carbide (SiC) particles. This material combines the advantages of metal and ceramic.

Significant characteristics:
-High thermal conductivity: Aluminum based silicon carbide materials have extremely high thermal conductivity, usually between 180-240 W/m · K, which can quickly transfer heat to the heat dissipation environment.
-Low thermal expansion coefficient: Its thermal expansion coefficient can be adjusted, generally between 6.5-9.5 × 10 ⁻⁶/K, which matches well with the thermal expansion coefficients of semiconductor chips and ceramic substrates, effectively preventing fatigue failure caused by inconsistent thermal expansion.
-Low density and high strength: The density of aluminum based silicon carbide is about 2.95-3.1 g/cm ³, which is comparable to aluminum, but its strength is close to steel, and it performs well in scenarios where lightweight design and high strength are required.
-Good mechanical performance and wear resistance: It has excellent bending strength (up to 400 MPa) and wear resistance, and can work stably for a long time in harsh environments.
-Corrosion resistance: It has good corrosion resistance to most chemicals and is suitable for use in various complex environments.
-Machinability: It can be processed through various processes such as electrical discharge, diamond, laser, etc., and can meet the manufacturing of heat sinks with complex shapes and high-precision requirements.
