Aluminum Silicon Carbide is a metal-ceramic composite material consisting of silicon carbide particles dispersed in a matrix of aluminum alloy. The SiC volume content is adjustable during the 15-70% range. AlSiC can be used in applications: heat sinks for electronic chips (special-purpose integrated circuits) and power supply modules, microprocessor covers and heat sinks, and covers or bottom heat sinks for computer chips (CPUs) and server chips (MPUs).HM can supply high-precision and competitively priced Al-SiC heat sinks with tight tolerances according to specific drawings. Various specifications are available for choices.

Aluminum Silicon Carbide Heat Sink Specification

Aluminum Silicon Carbide Heat Sink Advantages

• Composition
  Aluminum silicon carbide is a ceramic silicon carbide particle-reinforced aluminum matrix composite. It combines the different advantages of silicon carbide ceramics and metallic aluminum.
• Structure
  Aluminum silicon carbide is made by infiltrating molten aluminum into the three-dimensional network structure of foam silicon carbide with a dual network structure of SiC and Al.
• Thermal conductivity
  Aluminum silicon carbide has high thermal conductivity, with a thermal conductivity range of 180 to 220 W/m-K, much higher than many other materials.
• Coefficient of thermal expansion
  Aluminum Silicon Carbide's coefficient of thermal expansion matches that of chips (e.g., Si, GaAs), preventing fatigue failure due to thermal stress.
• Mechanical Properties
  Aluminum silicon carbide is characterized by low density and light weight, as well as high hardness and flexural strength.
• Corrosion resistance
  Aluminum silicon carbide has excellent corrosion resistance and can work stably long in harsh environments.

Aluminum Silicon Carbide Heat Sink Applications

• Electronic packaging
  Aluminum silicon carbide heat sinks are widely used in IGBT substrates, T/R module packages, power device packages, flip-chip packages, photovoltaic packages, and high-power LED lighting heat sink substrates.
• Aerospace
  Due to its excellent performance, Aluminum Silicon Carbide is also widely used in the aviation and aerospace fields to ensure the stable operation of equipment in extreme environments.
• Automotive Electronics
  Aluminum silicon carbide is also used in automotive electronics modules to ensure the reliability and durability of in-vehicle electronics.
