0-1mm 3-5mm White fused alumina manufacturer

White fused alumina (WFA) is made of industrial alumina powder, which is melted in the electric arc at over 2000 degrees and then cooled, crushed, and shaped, magnetically selected to remove iron, and sieved into various particle sizes. White Fused Alumina has high purity, good self-sharpening, acid and alkali corrosion resistance, high-temperature resistance, and high hardness performance. It can be used to manufacture ceramics, refractory materials, etc.
