Technical Industrial Abrasion Resistance Alumina Ceramic Frame
Pressing Plate
Advantages
1. Name: Alumina Ceramic Frame Pressing Plate
2. Size: as customers' drawing
3. Al2O3 Content: 95%/99% alumina
4. Color: white or ivory
5. Working Temperature: 1600-1700 degree
6. Feature: high mechanical strength, good insulation&high wear
resistant, etc.
7. Application: for refractory furnace or kiln, electron vacuum
decices, spaceflights, pharmaceutical engineerings or other
mechanical applications
They are high corrosion and wear resistance and strong impact
resistance and delivers 10 times longer working life than metal
plunger. They give a longer life to the sealed packing material.
Feature:
1. Refractory
2. Long service life
3. High Polished Surface
4. Superior Mechanical Strength
5. Anti-high Corrosion and Wear Resistance
6. Good Insulation Performance
7. High Temperature and Pressure Resistance
8. High Purity Zirconia and Alumina Ceramic Materials
9. High hardness, long service life, not easy to break and wear
resistance
10.Non-conductive, anti-static, ceramic material itself with the
insulation of electricity and magnetism properties
11.Corrosion resistance, high temperature resistance, can be
applied to a specific environment, such as acid alkali resistance
