Min 95% AL2O3 Barmac Brown Aluminum Oxide BFA F12-F220 for Bonded Abrasives
1. Description of Brown Aluminum Oxide BFA
Brown Aluminum Oxide is also named as brown fused alumina, it is made by high-quality bauxite,coke
(anthracite) as main raw materials, melting in an electric arc furnace at a temperature over 2200℃,then
made into different grain size through cooling crystallization, sort, crush, magnetic separation , screen size,
blow cleaning etc..
Its main chemical composition is Al2O3 which is over 95%, it has the characteristics of high hardness,
great toughness and sharpness.
