Brown aluminum oxide powder 280 mesh

Brown fused alumina micro-powder for thermal spraying is made of high-quality bauxite, anthracite and iron filings. It is cooled and smelted in a high temperature by more than 2000 degrees in an electric arc. It is crushed and shaped by a jaw crusher and a ball mill. After magnetic separation, the sieve is divided into various kinds. Brown fused alumina micro-powder is acid pickled before siphoning or overflowing to get a higher purity micro powder than grains. Its compact texture, high hardness, suitable for the manufacture of ceramics, grinding of high tensile metal and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture advanced refractory materials.

Brown fused alumina micro-powder for thermal spraying is a generally used material in manufacturing abrasive products and refractory products. It is not so hard as WA grain. Meanwhile, it is very moderately cost-effecient material comparing with WA.Brown fused alumina micro-powder for thermal spraying is also a desirable additive to wear-resisting floor,non-skid tile, non-slip coating and plasma spaying.Acid pickled brown fused alumina micro-powder can also be used as material of polishing wax and oilstone.
