White Fused Alumina Grit 1-3mm Used in Polishing Floor White Aluminum Oxide Grits for Sandblasting White Corundum

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.

Product Feature

1. The Al2O3 purity is high(99%min). So the hardness & grinding ability is high with good grinding efficiency.

2. High wear-resistance. Even in high-temperature circumstances, the strength is still excellent.

3. The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and easy to scatter.

4. Low oil absorption especially for water-based paint.

5. Neutral property with PH value around 7-8.

6. High whiteness. It doesn't affect the color of paints or coatings adding Al2O3 powder.

7. Resistant to most corrosive alkali and acide. It doesn't dissolve in water.

8. Resistant to high temperature up to 1900 °C. 9. Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.

Applications

1.For Free grinding, such as glass industry. 
2.For Friction products and abrasion resistance ground.
3.For Resin or ceramic bonded abrasive,such as grinding wheels,cutting off wheels.
4.For Refractory Raw material, Wear-resistant and fire-proof products.
5.For Grinding and polishing ,such as gringing stone, Grinding block, flap disc.
6.For Coated abrasives,such as abrasive paper,abrasive cloth,abrasive belt.
7.For Producing mold of precision casting and Grinding, lapping and polishing media.
