Description

BROWN FUSED ALUMINA *5% AL2O3: Abrasive:F**-F**0 Refractory:**1MM, **3MM, **5MM, **8MM, etc. Powder:**0F, **0F, **0F, **5F, etc. Brown Fused Alumina is fused and crystalized under high temparature from a mixture of bauxite and other raw material which is brown and features high hardness and ***** Abrasives tools made of it are suitable for grinding metals of high- tensile strength such as carbon steel, general-purpose alloy steel, malleable cast iron and hard bronze, etc. It also can be used as refractory materals, chemical additives, precise founding and anti-sliding materials.
