White Corundum Grit White Fused Alumina With High Quality
WHITE FUSED ALUMINA
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.

WHITE FUSED ALUMINA FEATURES
White fused alumina(WFA) is made from high quality aluminium oxide powder/ alumina powder which melted point above 2200°C. It has high hardness, high friability, high purity. With the fine thermal stability of White fused alumina, it can be used for hook refractory material, refractory castables and other refractory materials.
WHITE FUSED ALUMINA ADVANTAGES
1. Cleaning metallic surfaceswith removal of material(abrasive effect)
2. Removing rust and scalefrom metallic surfaces
3. Removing tempering colour
WHITE FUSED ALUMINA APPLICATIONS
White fused alumina is a highly pure form of aluminium oxide which issuitable for use with stainless steel and aluminium. This iron-free reusable blasting medium is angular, brittle and hard. lt has apowerful abrasive effect on the surface being blasted.White fused alumina belongs to the group of fused alumina.
1.Sandblasting, polishing and grinding of metal and glass.
2.Filling of the paint, wear-resistant coating, ceramic, and glaze.
3.Making of oil stone, grinding stone, grinding wheel, sandpaper and emery cloth.
4.Production of ceramic filter membranes, ceramic tubes, ceramic plates.
5.Production of polishing liquid, solid wax and liquid wax.
6.For the use of wear-resistant floor.
7.Advanced grinding and polishing of piezoelectric crystals, semiconductors, stainless steel, aluminum and other metals and non-metals.
