FEPA standard F16 white fused alumina granule
Product Introduction of FEPA standard F16 white fused alumina granule
FEPA standard F16 white fused alumina granule is one of the most commonly used abrasive materials for abrasive tools. 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 aluminium oxide method in a fixing furnace. It is of excellent self-sharpening property, good toughness, and aggressive grinding ability.
