Product Feature of WA 320mesh-800mesh abrasive powder for Inox polishing
- The Al2O3 purity is high(99%min). So the hardness & grinding ability is high with good grinding efficiency.
- High wear-resistance. Even in high-temperature circumstances, the strength is still excellent.
- The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and easy to scatter.
- Low oil absorption especially for water-based paint.
- Neutral property with PH value around 7-8.
- High whiteness. It doesn’t affect the color of paints or coatings adding Al2O3 powder.
- Resistant to most corrosive alkali and acid. It doesn’t dissolve in water.
- Resistant to high temperature up to 1900 °C.
- 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 is the difference between suspension-treated white fused alumina powder and fine powders?
A: The suspension-treated WFA powder is of even particle size distributions. The white fused alumina fine powder always goes 200#-0,320#-0 produced by milling and gets particle size by mesh sieving.
Q: What are the differences 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: Do you have a MOQ of WFA grain?
A: Generally no limit of MOQ. Even 25kgs(1 bag)is ok for us. But the logistic cost will be higher than normal.
Q: How do you make quality control on White fused aluminum oxide powder before delivery?
A: Besides inspection items such as chemical, and 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: What are the differences between fused aluminum oxide powder and calcined aluminum oxide powder?
A: They are produced by different processes. For fused ones, it is a melting and fusing process at a temperature of 2250 °C. The hardness and grinding performance are better. For calcined aluminum oxide powder, they are produced by a calcining process in an oven or a Tunnel kiln at a temperature of 1300°C or 1800°C. Calcined aluminum oxide is with kinds of crystal shapes. The price of calcined aluminum oxide powder is always lower than fused ones.
Q: Are free samples available from you?
A: Yes, we provide free samples within 1 kg. Express costs have to be borne by customers.
