Super Wearing Resistance 2000 Machining Ceramic Parts Silicon Carbide Rings
Super Wearing Resistance Silicon Nitride Ceramic Ball
Description:
Silicon carbide is a new type of ceramics with high cost performance and excellent material properties.
Due to features like high strength and hardness, high temperature resistance, great thermal conductivity and chemical corrosion resistance, Silicon Carbide can almost withstand all chemical medium. Therefore, SiC are widely used in oil mining, chemical, machinery and airspace, even nuclear energy and the military have their special demands on SIC. Some normal application we can offer are seal rings for pump, valve and protective armor etc.
