Silicon Carbide |
 |
| The silicon carbide has advanced property of wear-resistance, anti-corrosive, high heat conductivity & low dilatability and good intensity. They are widely applied as piston ring, bushing, bearing and vane in kettle, pump and compressor. They are also widely applied in mould. |
