Product Description


Precision Hydraulic Zirconia Ceramic Piston With High Temperature Resistant​



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 insulating material.

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 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.

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.
