Brown aluminium oxide/brown fused alumina is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials.

4 . Brown Fused Alumina Application:
1 . brown fused alumina widely used to manufacture advanced refractory materials, castables, refractory bricks and so on.
2 . sandblasting - abrasive moderate hardness, high bulk density, free of silica, specific gravity, good toughness, is the ideal "green" type sandblasting materials, widely used in aluminum, copper profile glass, washed jeans Precision molds and other fields;
3 . free grinding - abrasive grade abrasive, used in the CRT, optical glass, single crystal silicon, lenses, watches and clocks, glass, jade and other areas of free grinding, is commonly used in domestic advanced abrasive;
4 . resin abrasive - Abrasive with color, hardness, toughness, the right type of particle section and edge retention, used in resin abrasive, the effect is ideal;
5 . Coated abrasive - abrasive is sandpaper, gauze and other manufacturers of raw materials production;
5 . Package
