Brown Corundum Surface Used For Sandblasting

Brown corundum is a high-performance abrasive material produced by smelting premium-grade bauxite, anthracite, and iron filings in an electric arc furnace at extreme temperatures. With an Al₂O₃ content of 95-97%, it delivers exceptional durability, along with trace elements like Fe, Si, and Ti that enhance its structural integrity. Renowned for its superior hardness (Mohs 9.0+), thermal stability, and corrosion resistance, brown corundum is the top choice for industrial sandblasting, refractory linings, and precision grinding.
