White Fused Alumina (WFA or WA) is an important raw material for advanced refractories and abrasives, a widely used raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding, and hundreds of other applications. As it is a very pure, low iron alumina, specific refractory applications include high tech refractory castables, isostatic pressed refractories, and pre-cast refractory shapes. The benefits of White Fused Alumina in these applications are high alumina content, low impurities, and stability at high temperatures.
