White fused alumina F240
Product Introduction of White fused Alumina F240：
White Fused Alumina F240 abrasive powder is an alumina powder that has been melted at a high temperature of 2300 degrees. Its particle size range is 25-75um, with an average particle size of 42-48um. Its powder particles are uniform, and its color is pure white without impurities. As a commonly used wear-resistant agent in industry, white fused alumina F240 has the characteristics of strong impact and extrusion resistance, high hardness, and high melting point. It can be used as a wear-resistant filler for various synthetic materials such as ceramics, resins, and polyurethane materials.
Applications:
- Semiconductor industry panel grinding, carbon fiber extrusion plate grinding, etc.
- Grinding tool products such as oilstones, grinding fluids, and diamond dry polishing wheels.
- Zinc-rich coatings, polyurethane coatings, and other coating products. Ceramic products such as alumina insulation board, alumina ceramic membrane tube, ceramic wear-resistant layer, etc. Precise grinding and micro blasting for Inox, aluminum alloy, tungsten-molybdenum alloy etc. Grinding and polishing of non-metallic products such as glass and ceramics. Reinforced wood flooring wear-resistant layer.
- Wear-resistant fillers for composite materials including glass, resin, and carbon fiber.
- Refractory & Precision Casting.

FAQ:
Q: What is the HS code of white fused aluminum oxide?
A: HS code is 2818109000.
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 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: 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.
