Metallurgical Aluminum Oxide Powder

Our company's metallurgical aluminum oxide powder is produced through high-temperature kiln roasting process, using bauxite, industrial alumina and other aluminum compounds as raw materials, and then processed by ball milling and air jet milling to obtain calcined alumina. As a metal material, it has the characteristics of high purity, stable high-temperature performance, uniform particle size, good flowability, high melting point, and good sintering performance. Metallurgical aluminum oxide powder is widely used in refractory materials, abrasives and polishing agents, as an additive in smelting aluminum alloys, steel, and iron to improve the strength and corrosion resistance of products. We can produce alumina powder with different particle sizes and distributions according to the needs of different customers, and can customize products with a purity of 98.5% -99.9%.
