Wear Resistance Zirconia Ceramic Threaded Rod , Alumina Threaded
Rod And Screws
Product Description
Advantages of Zirconia ceramic threaded rods and screws:
1. Refractory.
2. Long Service Life.
3. High polishing surface.
4. Superior Mechanical Strength.
5. High Corrosion and Wear Resistance.
6. Good Insulation Performance Precision.
7. High Temperature and Pressure Resistance.
8. High Purity Zirconia and Alumina Ceramic Material.
- High hardness, long service life, not easy to break and wear
resistance.
- Non-conductive, anti-static, ceramic material itself with the
insulation of electricity and magnetism properties.
- Corrosion resistance, high temperature resistance, can be applied
to a specific environment, such as acid and alkali resistance.
They deliver 10 times longer working life than metal rods /
tubes.
