Brown corundum
Brown corundum (CAS No. 1302-74-5) is made of bauxite and coke (anthracite) as the main raw materials. It is smelted at high temperature in an electric arc furnace. The abrasive tools made of it are suitable for grinding metals with high tensile strength, such as various general steels , Malleable cast iron, hard bronze, etc.
product Introduction
Brown corundum (CAS No. 1302-74-5) is made of bauxite and coke (anthracite) as the main raw materials. It is smelted at high temperature in an electric arc furnace. The abrasive tools made of it are suitable for grinding metals with high tensile strength, such as various general steels , Malleable cast iron, hard bronze, etc. It can also be used to manufacture high-grade refractory materials. Brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance.
