Product Description


Alumina oxide blasting media white corundum powder

White fused aluminum oxide powder is an excellent polishing powder for stainless steel, aluminum alloy, copper, glass, and other materials. White fused aluminum oxide powder from us is an electrofused aluminum oxide powder. It is an aggressive grinding powder with high hardness, good toughness. White aluminum oxide is suitable not only for direct polishing with a micro polishing machine, but also suitable for making lapping products such as polishing wax, polishing stone, polishing liquid, etc. In the meanwhile, white aluminum oxide is an ideal additive for wear-resistance coating and ceramics.





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 acid. 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.

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 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: 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, 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 difference 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. white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder white corundum powder
