WA Abrasive grain for resin bonded disc
WA Abrasive grain for resin bonded disc is made from fully fused Aluminum oxide material. As one of the mostly used abrasive grain, WFA obtain excellent self-sharpening capability, good grinding performance. Especially for Stainless stell, metal alloy, resin bonded disc made from WFA grain acheive superior performance. In the meantime, the cost of white fused alumina WA material is much lower than Zirconium Alumina and SG abrasives.
