White Fused Alumina Powder
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.Get more news about high quality fused alumina,you can vist our website!
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.
White fused alumina is made of high-quality aluminum oxide powder and crystallized by electric melting. It has high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than brown fused alumina, and its toughness is slightly lower. Strong grinding ability, low heat generation, high efficiency.Abrasive tools made of white fused alumina are suitable for grinding high-carbon copper, high-speed steel, etc. White fused alumina is a medium-to-high-grade refractory raw material, with white color and dazzling crystal, which has the advantages of large bulk density and low porosity. It can effectively improve the volume stability and thermal shock resistance of the material. Fused white alumina is the main raw material for the production of medium and high-grade monolithic and shaped refractories. It is used for large-scale ladle, castable for medium and high-grade iron runner, gunning material, prefabricated parts and other unshaped refractory materials. The main raw materials for various corundum products, such as corundum bricks, corundum and mullite corundum saggers, corundum porous plug bricks for refining, integral spray guns and combined nozzles, high-temperature industrial furnace lining materials.
Abrasives are made of calcined alumina or industrial alumina as raw materials, melted at high temperature and then cooled. After crushing and shaping, magnetic separation, iron removal, screening and other steps, the production process is rigorous, the product quality is high, the texture is dense, and the purity is high. The particle size is uniform, let's take a look at the introduction of the general particle size of white fused alumina:White fused alumina is suitable for manufacturing ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc. It can also be used for manufacturing high-grade refractory materials. The code "WA" is consistent with international general standards and national standards. Most of them are for export, and there is also a certain amount for domestic users. The particle size of white fused alumina is produced according to international standards and national standards, and can be also processed according to user requirements.
