Alumina Ceramic Parts Fabrication
Aluminum Oxide Ceramic, Al2O3
Alumina ceramics can withstand more than 1000 degrees of high temperature, It is a kind of material with good thermal conductivity and insulation. After sunlight, the internal composition of the aluminum oxide ceramic changes, the color will be pale yellow, and its hardness is second only to diamond, industrial alumina ceramics are mainly used to make corrosion-resistant, wear-resistant parts.
molding and machining
- Molding ( Dry Pressing, Injection, Isostatic Pressing)
- Grinding (Surface Grinding, Cylindrical Grinding, High precision internal grinding)
Grinding can be used to machine various structural characteristics of Alumina ceramic parts with complex structures according to different characteristics.
- CNC Machining (Drilling, Milling, Turning, Honing)
- Polishing/Lapping
