Grade 1 White Fused Alumina 70 Grit White Aluminum Oxide Abrasive

White fused alumina abrasive is a type of abrasive with over 99% content of electrically fused aluminum oxide. It can not only be used for producing abrasive tools but is also widely applied in sandblasting industrial components such as metals, stainless steel, glass, and aluminum alloys. It increases the surface roughness of workpieces requiring sandblasting treatment, providing a foundation for subsequent painting and enhancing the adhesion of coatings.

Main Performance Characteristics of White Fused Alumina:

1. High purity of aluminum oxide (over 99%), resulting in high hardness, strong grinding power, and high grinding efficiency.

2. The white fused alumina grit produced by our company is made from grade 1 block material from fixed furnaces, with better toughness than that from tilting furnaces. As a raw material for abrasive tools, it enhances product sharpness, and as a sandblasting material, it offers better durability.

3. White fused alumina has uniform particle size. Compared to consumables like natural emery and glass beads, it is less likely to clog nozzles and has high particle consistency.

4. White fused alumina grain and fine powder have low sodium content (within 0.3%). As refractory castables and aggregates, they improve the erosion and corrosion resistance of refractory materials.

5. White fused alumina micro powder is produced through a water-based process, resulting in more uniform particle size, no large particles, and no scratching of workpiece surfaces.

6. White fused alumina can also be directly used in grinding, polishing, surface treatment, sandblasting for rust removal, etc. It is suitable for both dry and wet sandblasting, surface roughening and polishing, surface treatment and passivation before coating, etc.

7. Electrically fused aluminum oxide sand has strong wear resistance, making it suitable as an additive material for wear-resistant products.

8. Strong chemical stability, high resistance to acids and alkalis, and insoluble in water.

9. Strong thermal stability, with wear resistance unaffected at high temperatures.

10. Produced through a special ball milling process, it has low metal residue, high whiteness, and does not affect the color of coatings and other products.

11. White fused alumina has high refractory temperature, resistance to acid and alkali corrosion, and good thermal properties. It is not only used for grinding and polishing but also as an additive material for coatings, ceramics, rubber, plastics, and composites.
