1.Manufacture Aluminum Oxide Abrasive for catalyst carrier
2.Hardness :Morse :9
Brown aluminum oxide abrasive fused alumina refractories hardware is electrically fused in
an arc furnace from a mixture of bauxite at high temperature. It has brown colour, high hardness and
great toughness. The abrasives tools made of brown aluminum oxide are suitable for steel, malleable
cast iron and hard bronze. It used for refractory aluminum oxide lining mixture, pouring materials castable, etc.
