1. Product Description of Brown Aluminum Oxide Emery Powder

Brown Aluminum Oxide is also named as brown fused alumina, it selects the 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...

It has wide applications,which is called as the teeth of industry.
