Abrasive Brown Fused Alumina/BFA/brown aluminium oxide

Abrasive Brown Fused Alumina/BFA/brown aluminium oxide

Brown fused alumina is is also called brown aluminum oxide, which is fused and crystalized at high tempreture based on a mixture of bauxite and other materials. It is characterized by its high hardness, good toughness and sharp shapein size. Abrasives tools made of it are suitable for grindind metals of high-tensile strength such as carbon steel, general-purpose alloy steel, annealed malleable iron and hard bronze,etc. it also can be used as refractory materials

Advantage

 1. Brown corundum is characterized by high purity, dense texture, large stacking density, strong self-sharpness, good toughness and extremely low magnetic content;

2. The grinding tool made of it has the advantages of sharp grinding, low heating rate, high grinding ratio and less adhesion in use;

3. The sintered abrasive tool has the characteristics of deep blue color, no network crack and no rust spot after firing.
