China Al2O3 99.5% White Fused Aluminum Oxide Grains for SBlasting Polishing

Al2O3 99.5% white fused aluminum oxide grains for Sand blasting polishing

White fused aluminum/white corundum/WA, a kind of high-grade refractories, 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.
Product Descripition

White Fused Alumina for sandblasting
White fused alumina for sandblasting abrasive is processed by high quality corundum as raw material and
utilized by unique advanced technology. It is characterized by short grinding time, high efficiency, good
returns , low price and so on. In particular, its advantages such as high hardness, big specific gravity, good
chemical stability and unique self-sharpening , it becomes the first choice for the sandblasting technics,
meanwhile, it is also the ideal material for sandblasting and derusting, workpiece cleaning, and polishing.
White Fused Alumina For Precision Casting
White fused alumina is the high grade refractory raw material, main crystal system isα- Al2O3, white color.
It is characterized by high volume density, low apparent porosity, stable volume and thermal stability
performance and so on, it is can be used for shell making material of heavy steel casting, especially the alloy
casting, core sand, coating material and melt film precision casting, and it is also can be used as half precision
blasting and precision blasting material for hardened steel, alloy steel and so on.

White Fused Alumina for abrasive
This kind of 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,
acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-
speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives , polishing,
precision casting and so on.
White Fused Alumina for refractory
Comparing with brown fused alumina. It is also characterized by its high purity, acid and alkali resistance,
good thermal stability. It's the high grade refractory materials.
