Quick Details
Specifications
The major properties of sintered silicon carbide of interest to the engineer or designer, are as follows:
High hardness (second only to diamond)
Low density 40% the density of steel – approximately the same as aluminium
Low porosity
Good wear resistance in sliding and abrasive environments
Excellent corrosion resistance in most chemical environments
Low thermal expansion and high thermal conductivity leading to excellent thermal shock resistance.
