#150 white fused alumina is a fine-grained high-grade abrasive material with high purity, low iron content and excellent self-sharpening performance. It produces little heat during grinding, effectively avoiding workpiece burning and scratches, ensuring a high-quality surface finish. With uniform grain size, low dust and stable performance, it is widely used in precision grinding tools, fine polishing, sandblasting and surface treatment of stainless steel, high-speed steel and non-ferrous metals.
