Product Description

Brown fused alumina is fused and crystallized under high temperature from a mixture of bauxite and other raw materials. It is characterized by its high hardness, good toughness and sharp shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel, general-purpose alloy steel, annealed malleable iron and hard bronze, etc. It also can be used as refractory materials. Refractory alumina crude: 0 *1mm, 1 - 3mm, 3 - 5mm, 5 - 8mm, 8 - *5mm; Special grains for bonded abrasives: F8 - F**0; Special grains for coated abrasives: P8 - P**0, or at buyer's option.
