White fused aluminum oxide polishing powder 2500# (W7) for alloy material grinding
Characteristics of white fused aluminum oxide powder:
High purity of aluminum oxide (above 99.5%), resulting in high hardness, strong grinding ability, and high grinding efficiency.
Produced by water process, with more uniform particle size, no large particles, and will not scratch the workpiece surface.
Strong chemical stability, high resistance to acids and alkalis, insoluble in water.
Strong thermal stability, wear resistance at high temperatures remains unaffected.
High whiteness, will not affect the color of coatings and other products.
Wide range of applications, not only for grinding and polishing but also as an additive material for coatings, ceramics, rubber, plastics, and composite materials.
Product Feature of white fused aluminum oxide powder
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.
