Silicon Carbide SiC

Silicon Carbide is a light, extremely hard, and corrosion resistant material which makes it a strong candidate for wear applications in the harshest environments. Silicon Carbide also offers other desirable properties such as excellent thermal conductivity and high young modulus.

Applications

  • Semiconductor Process Equipment Parts
  • General Industrial machinery parts
  • Abrasion resistance part
