Grinding and Cut off Wheels Raw Materials White Fused Alumina

White Fused Alumina Grit was made from 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 high bulk density and low porosity and good volume stability and thermal shock resistance. As the most commonly used corundum in the abrasive industry, white fused alumina grain has a long history in applications because of its high hardness, good self-sharpening advantages.

Aluminum oxide is used successfully for cleaning, deburring, surface finishing, rust removal and old paint coatings, preparing surfaces for subsequent anti-corrosion treatments with paint and primer at the highest quality standards.
