Brown fused alumina /Brown aluminium oxide abrasive is fused and crystallized under high temperature from a mixture of bauxite and other materials. It is characterized by its high hardness, good toughness and sharp shape in particles. Suitable for grinding metals of high-tensile strength such as carbon stele, general purpose alloy steel, malleable cast-iron and hard bronze etc.Black silicon carbide

Black silicon carbide is produced at high temperature in electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between Aluminum Oxide and Synthetic Diamond.

Mechanical intensity of it is higher than Aluminum Oxide. It is brittle and sharp and has electrical and heat conductivity in some degree. It is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface gringing, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, ceramic, etc. It is also broadly used as high-grade refractory material and metallurgical additive.

We can supply quality Black Silicon Carbide grains based on ISO standard, FEPA standard, P standard for coated abrasives & JIS standard. Grits availabe are as following:

FEPA standard: F12~F240

ISO standard: F12~F240
