  • White Fused Alumina

Product Description And Parameters

Main Composition:Al2O3

Color:White

Capacity:1000 tons per month

Package:Export ton bag

Size:As your requirements

White fused alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. It is the main raw material for the production of medium and high-end shaped and unshaped refractory materials, and is also widely used in the manufacture of ceramics and resin abrasives And sandblasting, grinding and polishing, precision casting, special ceramics and other industries.

Features
1.High hardness.
2.High density.
3.Low porosity.
4.Highly resistant to heat and abrasion.

Application
It can be used for surface processing of metal or non-gold layer and it can be used for pretreatment process such as rubber coating,electronic parts and magnetic core flash processing,stress relief treatment in precision industries.
