Name: Customized Zirconia ceramic guide pulley

Zirconia Ceramic is with higher density, higher hardness and wear resistance characteristics etc, especially its bending strenghth and fracture toughness are very much higher than other non metallic materials, the service life is 3-5times of alumina ceramics. zirconia ceramic is widely used in various industries.

The chemical properties are as follows :
Bending strenghth : 800 Mpa
Fracture toughness : 6-8 Mpa.m3/2
Density : 5.8-6.02 g/cm3
Thermal conductivity Coefficient : 2.5-3
Mon's Hardness Scale : 8.5
