Reaction Bonded Silicon Carbide/SiSiC Rod

Formula: SiC
Form: Rod
Material: Reaction Bonded Silicon Carbide/SiSiC
Commodity: Ceramics
Reaction Bonded Silicon Carbide/SiSiC Rods are an advanced ceramic material that we produce in a choice of 6 diameters and lengths. This advanced ceramic combines silicon carbide grains and silicon. Its properties include high hardness, wear resistance, and strength retention at high temperatures. These rods are used in mechanical seals, bearings, valves, and other demanding applications requiring dimensional stability, stiffness, and wear resistance when exposed to extreme heat in oxidizing and corrosive environments. We offer Reaction Bonded Silicon Carbide/SiSiC Rods in 6 variations to suit different design needs.
