SiC chemical and physical properties

Silicon carbide is a synthetical material with outstanding hardness only superseded by diamond, CBN and B4C. The chemical inertness to most of the alkaline and acids in combination with its excellent heat and abrasion resistance make silicon carbide very suitable under extreme operation conditions.

Vickers Hardness 30 GPA Thermal conductivity 41W/m 0K

Thermal expansion 5× 10-6 /0K Specific gravity 3.21 g/CCM

We cover your every application

We supply you with abrasive grains, wiresawing grains, high performance powders, refractory, metallurgical grains, bonded abrasives, coated abrasives and superabrasives in forms of silicon carbide, aluminium oxide, diamond and cubic boron nitride.
