White Fused AluminaDWA
Description:
DWA is a high purity alumina with controlled crystallization obtained by melting calcined alumina in an electric arc furnace. Its controlled high purity and low iron content give them a high abrasive power and excellent cutting quality. DWA is especially adapted to the production of bonded abrasive or coated abrasive for grinding wheels, polishing wheels, segments, laps and etc.
