Product Description

Product Description

 

 

  White Fused Alumina (WFA/WA)

       White fused alumina (WFA/WA) is a raw material for production of refractories material. It also called white corundum or white aluminum oxide. 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.
