A grit Brown fused aluminum oxide 36MESH 46MESH
Brown fused alumina grit is a basic abrasive grain for making abrasive tools and abrasive blasting. It is produced from natural bauxite mine by a fusing process. After fusing and melting at about 2000 centigrade, it turns to a kind of artificial brown fused alumina. The main chemical of brown fused alumina is Al2O3. So it also be called brown aluminum oxide.
With different milling technology, there are several types of brown fused alumina. They are available for different applications such as sandblasting, resin bonded abrasives, vitrified bonded abrasives,anti-skid materials,etc.

Package of A grit Brown fused aluminum oxide:
Q:Is your company manufacturer or trading company?
A: We are a manufacturer of fused alumina and silicon carbide from 1999. And we also export related products in the abrasives industry.
Q: Are the brown fused alumina grits you get is produced from a Tilting furnace or a Fixing furnace?
A: We have both types of brown fused alumina grits made by Fixing furnace and tilting furnace. Generally, the one made by tilting furnace get better grit shape and high purity.
Q: How many grades of brown fused alumina do you have?
A: With different Al2O3 content, we get four grades. Better quality with higher purity.
Q: Do you have a MOQ of brown fused alumina grit?
A: Generally no limit of MOQ. We can even deliver 1bag(25kgs).
Q: How do you make quality control on brown fused alumina before delivery?
A: We will check the quality of including chemical content, particle size distribution, milling toughness of brown fused alumina, Bulk density of white fused alumina,etc.
Q: Do you get an certificate for abrasive grain?
A: We get ISO9001:2015 certificate.
