Description of Alumina Ceramic Parts
Aluminum Oxide (Alumina) is Widely Used Due to Its Versatility and Cost-Effectiveness Compared to Other Advanced Ceramics. Alumina Provides High Electrical Insulation, High-Temperature Resistance, Hardness, Wear Resistance, and Chemical Stability, Making It Ideal for High-Temperature and Corrosive Environments.
Our Factory Produces a Range of Alumina Purity from 75% to 99.8%. All Ceramic Parts We Supply Feature Dense Bodies Formed through Dry Pressing, Hot Pressing, Ceramic Injection Molding, and ISO Pressing. To Meet Special Applications, We Offer Secondary Processes Post-Sintering, Including CNC Machining, Polishing, Glazing, and Metalizing.
We Manufacture a Diverse Array of Alumina Ceramic Products, Including Tubes, Rings, Discs, Rods, Arms, and Wire Guides. Whether for Prototyping or High-Volume Production, We Are Confident We Can Provide the Ideal Solution for Your Needs.
