Artifical abrasives/ brown fused alumina/BFA powder

oduct Description

The main material of Brown Aluminium Oxide is bauxite, which is electrically fused at high temperature. It is brown and features high hardness and toughness. The abrasive tools made by Brown Aluminium Oxide are suitable for grinding carbon steel, malleable cast iron, hard bronze etc.In addition, it is also widely used in refractory materials, chemical additives, precision casting and antiskid material, etc.

Used：

making grinding wheels,sand paper,refractories,polishing,etc，coated abrasives

220# - 2000# brown corundum powder fro abrasive / polishing

What is Brown Fused Alumina

Brown fused alumina is bauxite, coke, anthracite as main raw materials, in the Canon of high temperature smelting electric arc furnace, the main chemical composition of AL2O3, TiO2 loop contains a small amount of SiO2 and Fe2O3, microhardness HV1800-2200, high toughness than SiC, use it made of abrasive, suitable for grinding the high tensile metals, such as all kinds of steel, malleable cast iron, hard bronze, etc., also can make advanced refractories.

Level of Brown Fused Alumina

Corundum principal component is the alumina, aluminum content hierarchical is used to distinguish, the lower the aluminum content is, the lower the hardness.

Specification:

High purity and low sodium white fused alumina is high purity α-type alumina powder containing no less than 99.7% AL2O3. This product is developed to maintain a low NA2O amount, as low as 0.15% or less, so it has an exntinsulation capacity. It can be used as insulation coating material for a heater of electronics tubes and various insulating film materials.
