White Fused Alumina 3-5mm (Refractory Grade)

Our range of White Fused Alumina 3-5mm (Refractory Grade) is produced by fusing alumina block in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of Alpha Alumina.
The application scope of WFA:
1. Lapping
2. Polishing
3. Coating materials
4. Catalyst carrier
5. Special ceramics
6. Precision casting
7. Advanced refractory materials
8. The abrasive tools made of it are suitable for grinding high carbon steel, high-speed steel and chilled steel
We can supply WFA with refractory grade and abrasive grade.
