1. Brown Fused AluminaBrown Fused Alumina is fused and crystallized under high temperature from mixture of bauxite and other materials, characterized by its high hardness, good toughness and sharp shape in particles. Abrasive tools made of it are suitable for grinding metals of high-tensile strength such as carbon steel, general purpose alloy steel, malleable cast-iron and hard bronze etc. It also can be used as refractory materials.2.semi-friable fused aluminaBrown semi-friable fused alumina (F grit) is low titanium brown fused aluminum oxide. We call semi-friable alumina. It has higher hardness and friability ability compare with BFA. It offer good cutting performance in fast and can be widely used in boned abrasives for working with heat sensitive metals and alloys, soft non-ferrous metals and rubber plastic, wood etc3.abrasive4.refractory materials
