White fused alumina is made of high quality alumina oxide powder as raw material, refined and crystallized by electric melting. It has high purity, good self-sharpening, high temperature resistance and stable thermal performance.
Wholesale white corindon for coated abrasives was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.White corindon is white with the main crystal phase alpha-Al2O3.The White corindon 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.
Purpose:
1.Bonded abrasives and Coated abrasives
2.Floor/Wall Laminates
3.Thermal Spraying(Plasma Spraying)
4.Lapping & Micro-blasting applications
5.Surface preparation and finishing
6.Super Refractories,Ceramics and Tiles
7.Brake linings
White fused alumina is made of high quality alumina oxide powder as raw material, refined and crystallized by electric melting. It has high purity, good self-sharpening, high temperature resistance and stable thermal performance.
White Fused Alumina (white corundum)
WFA Abrasive blasting media is made of 99% aluminum oxide powder as raw material, which is refined and crystallized by electric melting (thus white corundum is also called fused alumina and white fused alumina). The white corundum sand produced by our factory has high purity, low impurities, low sodium content, uniform particles and high whiteness.
Brown fused alumina for abrasive
1. Description:
Brown Fused Alumina is made from high quality bauxite by fusing in an electric arc furnace at high temperature. It has good toughness and high hardness. It is suitable for manufacturing of vitrified and resin bonded tools, and for lapping polishing and sand blasting. It can be also used to make superior refractory products.

white fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency.
White fused aluminum oxide becomes the first choice for the sandblasting technics, meanwhile, it is also the ideal material for sandblasting and workpiece cleaning, and polishing.
