Alumina ceramics are a type of structural ceramic with characteristics such as insulation, high strength, good thermal conductivity, and stable performance. Used in the electronics industry, insulation products, vacuum parts and other products. Usually using hot injection molding and dry pressing techniques
Reasons for choosing alumina ceramic products:
1. High hardness.
2. Good heat resistance.
3. Affordable price with high cost-effectiveness.
4. Long service life.
