Product Description
Al-SiC materials provide superior thermal management for high technology electronics applications in a lightweight, cost-effective material.

Al-SiC C is a composite material that combines Silicon Carbide particles in an Aluminum alloy matrix. It provides lightweight, high thermal conductivity and controlled thermal expansion.

AMETEK can supply Al-SiC in either plated or unplated versions to customer specifications.

Key Advantages
  • Superior thermal properties compared to other silicon carbide aluminum products.
  • Thermal expansion is closely controlled to match the components used in electronic packages.
  • Offered in both simple and complex fabricated shapes and in any variety of net shaped parts.
  • Cost-effective solutions for many thermal management problems.
  • Manufacturing process does not require a separate preform to produce the composite product.

Key Applications:
Al-SiC C is ideal for use in such electronic products applications as:
  • Chip mounting
  • Electronic packages
  • Circuit boards
  • Power supplies
  • Thermal spreaders
  • Lids and covers
Material Status 
  • Commercial: Active
  • Asia Pacific
  • Europe
