Product description
White Fused Alumina white Aluminum F220 Sand White Corundum Grain/sand Bonded Abrasives and Coated abrasives
White Fused Alumina white Aluminum F220 Sand White Corundum Grain/sand Bonded Abrasives and Coated abrasives 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).
White Fused Alumina white Aluminum F220 Sand White Corundum Grain/sand Bonded Abrasives and Coated abrasives 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. Highwear-resistance. Even in high-temperature circumstances, the strength is still excellent.
3. White Fused Alumina Sand White Corundum Grain is suspension treated by water. So it is of flow ability 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 acid. It doesn’t dissolve in water.
8. Resistant to high temperature up to1900 °C.
9. Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.

FAQ
Q: Are you a manufacturer or trading company?
A: We are a professional manufacturer of white fused aluminum oxide. HAIXU Abrasives has white aluminum oxide manufacturing experience of 22 years. The white fused aluminum oxide powder is one of our best sellers.
Q: What are the difference between the FEPA standard and the JIS standard for aluminum oxide powder?
A: They defined the particle size range with different standards. FEPA standard gets 14 grits from 63um-1 um. While JIS standard gets 19 grits from 63um-1um.
Q: How do you make quality control on White fused aluminum oxide powder before delivery?
A: Besides inspection items such as chemical, density, we check aluminum oxide powder sizes during and after production for each batch. We also keep samples of each batch for 3 months.
Q: Are free samples available from you?
A: Yes, we provide free samples within 1 kg. Express costs have to be borne by customers.
