Product Description

 Sand Blasting media 30#36#46# Brown Fused Alumina 

Sandblasting Materials Brown Corundum Brown Fused Alumina f16  is produced by a reduction fusion of high quality bauxites in electric arc furnaces. It is both a hard and tough material with high strength, making it an excellent abrasive grain for applications such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding. Its thermal properties make it an excellent raw material for refractory applications.

♦Brown fused alumina  for Refractory,Casting etc ♦Brown emery for Bonded abrasives and Coated abrasives

♦Brown fused alumina for Surface treatment/finishing

♦Brown fused alumina  for Lapping, polishing,decorative non-skid tile, and pressure blasting

♦Brown fused alumina  for Ceramic Tiles special ceramics

♦Brown fused alumina  for Fluidized Bed Furnaces and Skin / Dental Care

♦Brown fused alumina for Grinding high carbon steel, high-speed steel and chilled steel

(1)due to the high temperature resistant, corrosion resistant, high strength, such as performance, so use casting steel slide gate, and special alloy smelting rare metals, ceramics, blast furnace lining (wall and pipe); Physical and chemical vessels, spark plugs, heat-resistant oxidation coating.

(2)because of the characteristics of high hardness, good wear resistance, high strength, in the chemical industry system, used for all sorts of reaction vessel and pipe, chemical pump parts;

To do mechanical parts, all kinds of mold, such as wire drawing die, such as pencil lead mold mouth; Do abrasive tool, mould, bulletproof material, human body joint, seal die ring, etc.

(3)brown fused alumina insulation materials, such as corundum light brick, alumina hollow ball and fibre products, widely used in various high temperature furnaces of furnace wall and furnace top, high temperature resistant and heat preservation.
