Precision Hydraulic Zirconia Ceramic Piston With High Temperature
Features of Zirconia Ceramic Plunger Piston :
1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice
for alumina wear parts.
4) High electrical resistivity: alumina is an electrically
5) High corrosion resistance: it is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
- High hardness, long service life, not easy to break and wear
- 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.
Ceramic rings made of an extremely hard and chip-resistant
zirconia-based ceramic. They exhibit superior wear resistance,
extra long life and unmatched performance. They deliver 10 times
longer working life than metal spacers.
