F46 grit white electrofused alumina
Product Introduction of F46 grit white electrofused alumina
F46 grit white electrofused alumina is an excellent raw material for abrasive tools. Bulk density is an important factor for bonded abrasive and vitrified abrasive wheels. The high bulk density of white fused aluminum oxide helps to make high-quality wheels. The white fused alumina F grit could be used for bonded abrasives such as cutting wheels, grinding wheels, vitrified grinding wheels, whetstones, etc. White fused alumina is made by a process of high-temperature melting aluminum oxide method in a fixing furnace. It is of excellent self-sharpening properties, good toughness, and aggressive grinding ability.
