Silicon Carbide
Silicon carbide seal faces, bearings, and bushings are engineered for demanding applications where high thermal conductivity, corrosion resistance, mechanical strength, and self-lubricating properties are essential. With a low thermal expansion and low coefficient of friction, silicon carbide components are ideal for extreme operating environments found in mechanical seals, gas seals, propulsion shafts, slurry seals, and radial/thrust bearings. These components are widely used across chemical processing, mining, pulp and paper, and refining industries for their durability and reliability.
Sintered Silicon Carbide (SSiC) is made from fine SiC powder with sintering additives and is formed using ceramic processing techniques, then sintered at 2,200°C in an inert gas. Known for its abrasion resistance, shock resistance, and low friction, SSiC offers outstanding performance against a variety of mating materials. Silicon carbide materials are commonly available in Alfa Sintered (SSiC) and Reaction Bonded (RBSiC) grades, tailored for high-performance industrial sealing and bearing applications.
- Superior wear resistance with low friction.
- High-temperature capabilities.
- Wide-ranging compatibility with other materials.
- High thermal conductivity.
- Outstanding thermal shock resistance.
- Superior corrosion resistance, especially in alkali environments.
