TufbideTM Silicon Carbide Materials

TufbideTM SA Sic is a fine grain, sintered form of alpha silicon carbide, with a density greater than 98 percent of theoretical (3.10g/cm3).It has a very fine microstructure(less than 10 μm) for excellent wear resistance and contains no free silicon, which makes it highly chemically resistant. The combination of fine grain structure and universal corrosion resistance results in a hard face material with excellent performance.

TufbideTM SB SiC is a sintered alpha silicon carbide designed specifically for optimum performance in sliding contact applications. This material contains significant amount of boron nitride(BN) solid lubricant enables it to perform well in marginal lubrication situations. even when it is running against itself (hard face vs hard face). The universal corrosion resistance of SiC and BN, combines exceptional wear resistance of TufbideTM SA SiC and excellent self lubricating characteristics of BN, making this material the ultimate choice for the most demanding applications.
