Customized Ceramic Shaft Of Silicon Carbide/Zirconia With High Precision
Description of ceramic shaft:
1. Silicon carbide shaft: Our silicon carbide is highly purified, sub-micron silicon carbide material after air pressure sintered, has high hardness Hv2800, wear resistance, resistance to various strong acids, strong alkalis, salt corrosion, high temperature resistance. Because of the properties of SSiC, this material are usually used in the petroleum, chemical, semiconductor, food machinery, pharmaceutical industry, etc.
2. Zirconium oxide shaft: Our zirconia material has a density and linear expansion coefficient close to that of metal steel shafts, high hardness Hv1300, wear resistance, resistance to various strong acids, strong alkalis, salt corrosion (except hydrofluoric acid), non-magnetic, non-conductive, high temperature resistance, high operating speed, impact resistance, small starting torque, resistance to dry friction,
