24mesh brown fused alumina abrasive grain
24mesh brown fused alumina abrasive grain 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 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.
