Regular Fused Alumina

A is the most widely known abrasive powder, popularly called alundum. This product is made by melting bauxite in an electric furnace at a temperature of 2000℃ to obtain aluminumoxide (Al2O3) corundum crystal of at least 90% purity. One special feature of this product is that the toughness (tenacity) of the abrasive particles has been increased by fusing them with a small percentage of titanium. As a result, A has the highest degree of toughness among all Fujimi abrasive powders. This product, which is manufactured to sustain a consistent distribution of particle sizes, is a highly efficient abrasive and will not scratch the surface of the workpiece, and maintains great stability as it functions as an abrasive. A is well suited for use as a material in super-finishing precision grindstones and super-finishing lapping cloth or paper. It is the most suitable abrasive powder for use on cathode-ray tubes and related glassware, and soft metals, where precision lapping is required.
