Material Notes:
Silicon carbide is extremely hard and displays excellent corrosion and thermal shock resistance. Its outstanding sliding properties and high thermal conductivity make useful in tribological applications. SSiC is resistant to all chemical media. Since no metallic silicon is present in the matrix, it can be used at temperatures up to 1600°C without impaired strength. Rocar® ST has excellent volume-production axial dry-press performance which, in turn, results in process reliability combined with lower production costs.
