Coated Abrasives Fused Aluminum Oxide Chemical Grade Alumina 60 - 80% AL2O3

Good Self - sharpness Fused Aluminium Oxide Black P12- P320 For Coated Abrasives

1. Product Description of Black Aluminium Oxide

Black fused alumina is also a kind of corundum,it is made by high iron bauxite, high alumina bauxite and iron

oxide as main raw materials,then smelted in the electric arc furnace completely, then made into different grit

size after different processes of cooling,crushing ,screening etc.

It has the characteristics of moderate hardness,good self-sharpness,strong cutting force,not easy to burn the

treatment and low cost.

2. Main Technical Index of Black Aluminium Oxide

3. Why Fused Aluminium Oxide Black Emery is used for Coated Abrasives?

Mixied black aluminium oxide with brown fused alumina to make sandblets, will achieve better polishing effect

in stainless steel compared with the one made by single brown fused alumina. It will not only greatly reduce the

cost of raw materials,but also make the final product performance more suitable for the treatment, improving

the grinding effect and achieve a higher price / performance ration.

Compared the pure coated abrasives made by calcined brown fused alumina,It has also achieved better

polishing effect and lower cost to mix black fused alumina with calcined brown fused alumina in a suitable

ratio to make coated abrasives to polish woods,metal etc.

Therefore,black fused aluminium oxide is suitable for making coated abrasives.

4. Other Applications of Fused Aluminium Oxide Black except for Coated Abrasives

• Bonded abrasives:Resin cutting discs;
• Polishing stainless steel tableware;
• Sandblasting media;
• Anti-slip aggregates & wear resisting pavement;
• Polishing Waxes;
• Refractory materials.
