Brown aluminum oxide（BA) is made from quality bauxite, coke (anthracite) by melting in the electric arc furnace, the product shows very good toughness, good self-sharpening, chemical stability, high temperature resistance, corrosion resistance.
Processing:
Quality bauxite → Fused → Block → Crushed → Sieving → Magnetic separation → Excellent sieving → Packing
Application:
Grinding Wheels / Cutting wheels / Cutting Discs
Sand Paper / Sand belts
Abrasive Blasting / Surface Preparation / Rust Removal
