Product Description

Brown aluminum oxide F24 F30 F40 for resin cutting disc

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.

Features of Brown aluminum oxide F24 F30 F40 for resin cutting disc:

  1. High hardness around Mohs 9.0.
  2. High toughness which is a little higher than white fused alumina.
  3. Good grinding ability.
  4. A quality level with high Al2O3 purity and low TiO2 impurity.
  5. Low Fe2O3 content with magnetic removal treatment.
  6. Good grain shape with high bulk density.

Brown aluminum oxide F24 F30 F40 for resin cutting disc Application:

  1. Bonded abrasives such as cutting disc, grinding disc,fiber disc,etc.
  2. Vitrified abrasives.
  3. Blasting media,surface treatment such as dust removal and cleaning.
  4. Anti-slip applications like floor, ceramics, auto brake parts

  • FAQ

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.

Q:Do you support third party inspection before delivery?

A: Yes, we support third party inspection.

Q: Do you accept OEM orders?
