Good Self-sharpness Aluminium Oxide Brown fused Alumina P12 - P220 for Coated Abrasives
1. Product Description of Brown Aluminium Oxide
Brown aluminium oxide is selected from high quality bauxite, coke, iron scrap as raw material,then
melting in arc electric furnace under high temperature over 2,000 degrees, finally crushed and screened
into different grit size.
