Hexoloy® SA SiC is produced by pressureless sintering submicron silicon carbide powder. The sintering process results in a self-bonded, fine grain (less than 10µm) SiC product which is extremely hard, lightweight and low in porosity. The material can be formed into complex shapes with greater than 98% theoretical density. Hexoloy® SA SiC is highly resistant to corrosion, erosion, sliding wear, high temperature and thermal shock.

Corrosion Resistance

The corrosion resistance of Hexoloy® SA SiC permits superior performance in environments of hot gasses and liquids including strong acids and bases, even at extremely high temperatures. The results (below) indicate that by comparison Hexoloy® SA SiC outperforms tungsten carbide and aluminum oxide in all chemical categories.

The ability of Hexoloy® SA SiC to resist corrosion along with its excellent surface finish characteristics makes it ideally suited to applications involving heat exchangers, mechanical seal faces, valves, bearings and other mineral and chemical processing equipment components.
