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.

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

Black aluminum oxide emery powder#325-0,#500-0,#1000-0 is suitable for making into a variety of polishing

waxes for fine polishing.
