Other spec are available upon request. Low sodium, Micro sodium WFA are both available.
White Aluminum Oxide Advantages
1. Low sodium and micro sodium WFA can be provided. Na2O of our micro sodium WFA is less than 0.1%, can be double 0.
2. High cleanliness, strong adhesion, high hardness and strong cutting force, whiteness can be based on customer needs.
3. High bulk density and high transparent wear-resistance sands can be provided. The crystal is rounder than normal ball mill WFA.
4. Various specifications can be supported, and the bulk density can be adjusted according to customer’s demand.
White Alumina Applications
1. It can be used for coated and coating abrasives, floor wear-resistant sand, ceramic roller professional sand, wet or dry blast sand.
2. It’s uitable for super-precision grinding , polishing sandblasting in the crystal and electronics industries.
3. It ‘s suitable for processing hardened steel, alloy steel, high-speed steel, high carbon steel and other materials with high hardness and high tensile strength.
4. It can also be used as contact media, insulators and precision casting sand.
