Aluminiumoxid weiß / Schleifmittel für Sandstrahlen

White fused alumina is made from high quality alumina by melting above 2000°C in the electric arc furnace and then cooling. It is with high purity, great self-sharpening, acid and alkali resistance, high temperature and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. It can be made to the abrasives, suitable for sandblasting and grinding high carbon steel and staining steel and other fine-grained abrasive; also be used for precision casting and high-refractory materials.
