Product Description
Brown Corundum for Abrasives and Refractories  

PROCESS OF PRODUCTION:

Brown fused alumina is produced from bauxite, charcoal, iron chip by being fused under high temperature in an electric arc furnace. It is characterized by high toughness and has a micro hardness of 2000-2200kg/mm2. The abrasive tools made by brown fused alumina are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze, etc. Brown fused alumina can also be used for making fine quality refractory etc.

APPLICATIONS:

Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening.

PACKAGING DETAILS:

25kg/bag, one inner plastic bag, two poly-woven bags or one coated poly-woven bag. Paper bag or carton packing is available. Wooden pallet or jumbo bag is also available
