Abrasives, lapping and polishing agents brown aluminum oxide 360mesh 400mesh 600mesh

Brown fused alumina is made of bauxite/anthracite coal. Abrasive tools made by brown fused alumina are suitable for metal with high tensile(like: steel, malleable iron, bronze etc).and suitable for grinding, polishing, blasting precision casting, and also for refractory material. Brown fused alumina with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength.

Abrasives, lapping and polishing agents brown aluminum oxide 360mesh 400mesh 600mesh

Brown aluminum oxide is made of high-quality bauxite, anthracite, and iron filings. It is cooled and smelted at 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. 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 aluminum oxide is a generally used material in manufacturing abrasive products and refractory products. It is not so hard as WA grain. The products made from brown fused alumina is very suitable for tough task like large sandblasting outdoor, rough grinding work, etc. Meanwhile, it is a very moderately cost-efficient material comparing with WA.
