Product Description

Better Self-sharpening Black Aluminum Oxide Fused Alumina P12-P320 For Coated Abrasives


1. Product Description of Black Aluminum Oxide Fused Alumina

Black Aluminium Oxide also named as black fused alumina,it is the fusion of high alumina bauxite,high iron

bauxite and iron oxides,melting in electric arc furnace under high termperature.

Its contains about 60-80% alumina,which offers the unique characteristics of moderate hardness,good

self-sharpness,it is not easy to burn the treatment surface compared with brown or white fused alumina.

Most importantly,the price of ordinary black aluminum  oxide is nearly 40% lower than the one of brown fused

alumina.

3. Why Black Aluminum Oxide P grit is suitable for making coated abrasives?

Mixied black fused alumina with brown fused alumina to make sandblets, has achieved 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 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 alumina is suitable for making coated abrasives.

And Saint-Gobian Group has been using our black aluminum oxide P grit for several years.
