A coated abrasive article includes a backing and fused alumina-zirconia abrasive grains attached to the backing with a binder. The fused alumina-zirconia abrasive grains include between about 35 wt% and about 45.5 wt% ZrO2+HfO2, between about 43.7 wt% and about 65 wt% Al2O3, less than about 0.8 wt% SiO2 and less than about 10 wt% other oxides. The fused alumina-zirconia abrasive grains simultaneously satisfy both a granulometric and densimetric condition.
