Hexoloy® SA SiC is a pressureless, sintered form of alpha silicon carbide, with a density greater than 98 percent theoretical. It has a very fine grain structure (4 - 10 microns) for excellent wear resistance and contains no free silicon, which makes it highly chemically resistant in both oxidizing and reducing environments.
The corrosion resistance of Hexaloy® SA SiC permits superior performance in environments of hot gasses and liquids including strong acids and bases, even at extremely high temperatures. The results indicate that by comparision, Hexaloy® SA SiC outperforms tungsten carbide and aluminum oxide in all chemical categories.
The ability of Hexaloy® SA SiC to resist corrosion along with its excellent surface finish characteristics makes it ideallu suited to applications involving heat exchangers,mechanical seal faces, valves, bearings and other mineral and chemical processing equipment.
