Good Self-sharpness Black Aluminum Oxide Emery Powder 325#,1000# for Polishing Waxes
1. Product Description of Black Aluminum Oxide Emery Powder
Black Aluminum Oxide is one kind of electric corundum with black color,so it is also called as black fused
alumina.It selects high alumina bauxite or high iron alumina, iron oxide as main materials,then completely
smelt in the tilting electric arc furnace, getting the first-garde black corundum crude,then finally crushed into
different grit size after series process such as cooling,crushing,magnetic separating,screening,inspecting,
packing.
Black aluminum oxide is one economic abrasive,its price is 40% cheaper than the one of brown fused alumina,
so it could partically replace brown fused alumina in many applications.

3. Main Production Process of Black Aluminum Oxide
4. Product Features of Black Aluminum Oxide Emery Powder
High Effciency
Strong cutting force and good self-sharpening which are able to improve the cutting or polishing efficiency.
Smooth finish with little surface discoloration
Moderate hardness,little heat generated in surface,not easy to burn the treatment surface when polishing or
cutting process,achieving smooth finish with little surface discoloration.
Better price /performance ratio
Cost is much lower than other abrasives(aggregate) with equivalent performance.
Environmental friendly
Waste comprehensive utilization, melting crystallization, noharmful gases generated in the whole production,
so it is one environmental friendly abrasive.
4. Main Applications of Black Aluminum Oxide Emery Powder
