Black Fused Alumina for Rust Removal:

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.
