Superior Materials for Military & Commercial Applications

At ASCM, we manufacture three products that can be customized to your specifications:

CVC SiC® – This high-purity, ultra-high temperature material is ideal for use in telescopes, optical applications and extreme environments. It is available in thicknesses ranging from 1mm to 75mm in a variety of shapes and sizes. Our unmatched combination of quality and flexibility make us your supplier of choice for optical grade, robust SiC.

Advantages of CVC SiC®

  • Purity greater than 99.99% (less than 5 ppm total)
  • Rapid growth rate (>5x CVD SiC)
  • Near net shaping (conformal deposition)
  • Diameters – up to 1500 mm
  • Inherently low stress
  • Low or high resistivity
  • High stiffness with low CTE
  • Dimensional stability
  • Inherently radiation hard
  • Associated rad hard and space hard coatings
  • Directly polishable


OMNI SiCTM (CVD SiC) – With a purity level that sets it apart, our OMNI SiC™ (CVD SiC) is ideal for use in Semiconductor manufacturing and silicon wafer processing. This material has excellent chemical resistance, outstanding machinability, high thermal conductivity, and long wear life. OMNI SiC™ is available in thicknesses ranging from less than 1mm to 15mm.

Advantages of OMNI SiCTM

  • Purity greater than 99.99% (less than 5 ppm total)
  • Low or high resistivity
  • Excellent chemical resistance
  • Diameters – 500 mm
  • Outstanding machinability
  • High thermal conductivity
  • Superior corrosion resistance
  • Long wear life

HoneySiC® – This lightweight wafer technology is exceptionally strong, making it ideal for use in microchips and complementary structures. We provide HoneySiC® in thicknesses ranging from less than 1mm to hundreds of millimeters with purity on par with our CVC® and Omni SiC.
