AL2O3 high precision customized sizes 95%-99.99% heating element alumina ceramic plate
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.
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.
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.
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.
