ABSTRACT:
This invention concerns the discovery that sol-gel process alumina abrasive grain provides superior performance in bonded abrasives for grinding cast iron. In a preferred form it is disclosed that bonded abrasives of sol-gel process alumina abrasives in combination with other abrasive grains such as those of silicon carbide and fused alumina also provide superior grinding of cast iron.
