High Precision Customized Alumina Washer Zirconia Ceramic
Piston/Plunger For Pump
Zirconia, Alumina ceramic are the most mature of the engineering
ceramics, offering excellent electrical insulation properties together with high hardness and good wear
resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally
white but may also be pink or ivory.
Our products include engineered ceramic, strengthened structure
ceramic,ceramic bar,ceramic tube,ceramic block, ceramic ring,
ceramic cylinder/bushings, ceramic shaft,ceramic plate,ceramic
sleeve,ceramic valve,ceramic plunger and ceramic arm,ceramic pin,
ceramic metric gauge, ceramic thin plate,etc.
Advantages:
1. Refactory.
2. Isostatic Pressed.
3. Long Service Life.
4. Superior Mechanical Strength.
5. High Corrosion and Wear Resistance.
6. High Temperature Resistance.
7. Good Insulation Performance Precision.
8. High Purity Zirconia and Alumina Ceramic Material.
Due to these outstanding properties, Ceramic Products are used in a
wide range of industrial and advanced appications.
And a lot of practical applications prove that our ceramic products
has reached a state of high standard and quality.
