BFA abrasive grain for rust removal

BFA abrasive grain for rust removal 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, surface treatment,resin bonded abrasives, vitrified bonded abrasives,anti-skid materials,etc. The higher Al2O3 purity, the higher hardness and better grinding performance.

Features of brown fused alumina grit:

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.

Application:

1.    Sandblasting on metal,iron,etc.

2.    Rust removal before coating.

3.    Grinding hardware accessories.

4.    Polishing stainless steel knife,etc.

5.    Blasting on tools such as machine borad,saws,etc.

6.    Grinding plastic parts.

7.    Non-slip material for floor.

8.    Surface treatment and cleaning.

9.    Vitrified abrasives.

10. Blasting media,surface treatment such as dust removal and cleaning.

11. Anti-slip applications like floor, ceramics, auto brake parts
