Brown fused alumina is fused in an electrical furnace by high temperature.its main raw materials 

are bauxite.anthracite.it dispaly brown.its chemical composition contains Al2O3,a small amount of 

SiO2.TiO2.and Fe2O3.etc.the microhardness is 1800-2200kg/mm2.

the toughness is higher than silicon carbide.abrasive articles made of it are suited for grinding 

metals of highten sile strength such as steel.annealed malleableiron and hard high-class 

refractory products.the degree of refractory is up to 1850 centgrade.

Application:

1) Abrasive: Produce ceramic gring wheel, resinoid gringding wheel, Grinding stone, Gringing block, sand paper, sand cloth, sand belt, polish wax, abrasive paste, coating etc..

2) Refractory material: Mainly used for abrasion and high temperature resiatant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc..

3) Sandblasting abrasive: Mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove oxide skin etc..

4) Abrasion resistance ground: Mainly used for non-slip of airport and road, chenmical factory

board paving.

5) Precision casting: Investment casting technics of stainless steel and aluminium casting in coating.
