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.
We are able to design and manufacture according to your specific dimensions with good quality and reasonable deliver time.
Advantages:
High temperature oxidation resistance
Excellent Corrosion resistance
Good Abrasion resistance
High coefficient of heat conductivity
Self-lubricity, low density
High hardness
Customized design.
