White fused alumina powder is made of high-purity low-sodium alumina powder by melting at the high temperature, cooling crystallization, and then crushing. The white fused aluminum oxide powder grit is under strict controlling to keep the grain size distribution and the consistent appearance.
The grain size distribution of the white fused alumina powder is narrow. After shaping processing, high purity white corundum powder has full grain, sharp edges and corners, high grinding efficiency, high polishing brightness. The grinding efficiency is much higher than the soft abrasives such as silica.
Because of the good appearance, the surface of the polished object has a high finish. Widely used in the grinding and polishing of semiconductors, crystals, circuit boards, aluminum, steel, stainless steel, stone, glass, etc. Especially in the industry of grinding and polishing of stainless steel, aluminum, copper and other metal materials and glass industry, it fully demonstrates the superior performance.
