Products Description
White fused alumina (WFA) is a raw material for production of refractories material. It also called white corundum or white aluminum oxide.
Comparing with the Brown fused alumina, it is more homogenous in terms of chemical composition, structure and properties.
The result is a product with high hardness, high friability, high purity, high melting point, and large crystal size.
It widely used in refractory industry, also can be used in ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications.

Production Process
APPLICATIONS
White fused alumina is a highly pure form of aluminium oxide which is suitable for use with stainless steel and aluminium.
This iron-free, reusable blasting medium is angular, brittle and hard.
It has a powerful abrasive effect on the surface being blasted.
White fused alumina belongs to the group of fused alumina.
