F12-240 WFA/ White Fused Alumina 

Product  Descripition

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.

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.
