Brown Fused Alumina Polishing

Product Description
Brown Fused Alumina is fused and crystallized under the high temperature of above 2250°C with high quality bauxite, carbon and iron as raw material.

Our product characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion, good corrosion-resistance and so on. Could not burst, no pulverization and crack in using course of refractory.

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.

Brown Fused Alumina is also called Brown Corundum, it is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials.

Brown Fused Aluminium Oxide BFA is widely used for Resin Bonded

Abrasives Vitrified Bonded Abrasives Sandblasting Polishing Surface

Preparation Our BFA has excellent hardness toughness sharp edge and

selfsharpening character hence is an ideal abrasive material It also has

a min of 95 Al2O3 content iron free high purity low magnetic contents

and extremely stable

White Fused Alumina polishing was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
