Refractory materials white fused alumina 0-1mm 1-3mm
WA Abrasive grain 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.
