1.Description:
White Fused Alumina (WFA) is produced from the fusion of industrial calcined alumina in electric arc furnace.
2.Characteristics
It characterized with high hardness, high purity, chemical stability, a high melting point, and good corrosion resistance.
3.Application
White Fused Alumina is widely apply to steel and foundry industries, castables, light-weight insulating refractories, high alumina refractory mixes, blast furnace linings. It also be used in many applications including grinding and cut off wheels, coated abrasives, investment casting shells, coatings, polishing, and etc.4.Specification
