Hard wearing zirconia ceramic substrate irregular shape zirconia ceramic sheet
Zirconia Ceramic
Zirconia offers the traditional ceramic benefits of hardness,wear
resistance and corrosion resistance,without the characteristic
ceramic property of absolute brittleness.
Features & Advantages
1. High strength
2. High hardness
3. Wear resistance
4. Non-magnetic
5. Electrical insulation
6. Corrosion resistance in acids and alkalis
7. Modulus of elasticity similar to steel
8. Coefficient of thermal expansion similar to iron
