White Fused alumina (WA)is white and harder and more brittle than Brown Fused Alumina Micropowder. It features strong cutting force, steady chemical property and excellent insulation. Its knoop's hardness is 2200-2300kg/mm2. It can be used for making bonded and coated abrasive tools, wet or dry blasting. It is suitable for grinding of the hard and strong bending strength materials, such as chilled steel, alloy steel, high-speed and high carbon steel and suitable for crystal, cutting semiconductor and monocrystalline and polycrystalline. Meanwhile, it can be used as insulation, special ceramics and super refractory materials, etc. Products are classified chemical washed, non-washed, shaped, non-shaped, normal bulk density and high bulk density. All products will be supplied according to customer"s different requirements.
