ANSI Standard White Fused Alumina F280# Abrasive Powder Exported to Europe and America
Suspension treated, water-washed overflow white fused alumina micropowder is produced from low-sodium aluminum oxide powder. It undergoes electric melting for crystallization, is initially ground into powder by milling machines, then acid-washed to remove impurities, and finally classified via hydraulic overflow. The complex processing results in a concentrated particle size distribution with no large grains, making it suitable for precision grinding and polishing. Due to its high chemical stability, hardness, thermal stability, and wear resistance, it is also widely used in wear-resistant coatings, industrial ceramics, and other industries.
White fused aluminum oxide F280 applied to ANSI standard is made from high-quality alumina by melting above 2000°C in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The white alumina produced in tilting electric arc furnaces has the advantage of high density, low porosity, good volume stability, and thermal shock resistance. As one of the most commonly used corundum in the abrasive industry, white fused alumina has a long history in applications because of its high hardness and good self-sharpening advantages. By adopting high-quality grade materials, a strict quality control system, and advanced production technology, HAIXU’s white fused alumina achieves high purity, stable quality, and good particle distribution.
The micro-powder from Haixu Abrasives is acid-washed and water-pickled, resulting in better purity and improved grit size distribution.
Features of ANSI Standard White Fused Alumina F280# Abrasive Powder Exported to Europe and America:
High purity of alumina (above 99.5%), resulting in high hardness, strong grinding power, and high grinding efficiency
Produced via water-based process, ensuring more uniform particle size, no large grains, and no scratching of workpiece surfaces
Strong chemical stability, resistant to acids and alkalis, insoluble in water
Excellent thermal stability, wear resistance unaffected at high temperatures
High whiteness, does not affect the color of coatings and other products
Wide range of applications, not only for grinding and polishing but also as an additive in coatings, ceramics, rubber, plastics, and composite materials
The electrofused aluminum oxide powder for polishing has outstanding features including small crystal size and impact resistance. By ensuring excellent purity, HAIXU Abrasive's product performs exceptionally well in sandblasting and as a raw material for abrasive tools. Users will experience multi-recycle usage and more durable performance.
