Black fused alumina for rust removal
Description
Black fused alumina, with moderate hardness, bigger toughness and wear-resisting sharp edges ; it will generate less calorific value during grinding and increase the pure degree of polishing machining, the polishing performance of Black fused alumina is much higher than other similar products, well applied in sandblasting sector to remove the rust on mental surface.
Advantages of Black fused alumina
- Moderate hardness
- High toughness
- Temperature resistance
- Stable thermal performance
Application of Black fused alumina
