Material Notes:

Rocar® is an extremely lightweight silicon carbide ceramic. It permits a reduction in mass forces at high speeds, and is considered for its hardness, excellent resistance to corrosion and sudden changes in temperature, excellent anti-friction properties, and higher heat conductivity over steel. The various types of Rocar include sintered and silicon infiltrated silicon carbide. 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.
