Brown Fused Aluminium Oxide (BFA) for Bonded Abrasives
High density sandblasting brown aluminum oxide
Brown aluminum oxide is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness, good toughness and 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 broze etc.It also can be used as refractory materials. Brown Fused Alumina is widely used in Bonded and Coated abrasives for the grinding of metals.
Usage:
grinding media, sandblasting media;
surface cleaning, grit blasting,
lapping, polishing, grinding,
sandblasting, etching
wet and dry blasting
mineral skin abrasion materials
metal finishing & surface preparation
refractors, ceramics, coatings
bonded & coated abrasives
