White Fused Alumina White corundum is made of industrial alumina powder as raw material and refined using modern new unique technology. Sandblasting abrasives have the characteristics of short grinding time, high efficiency, good benefits and low price. The main components: aluminum oxide (Al2O3) content is more than 98%, and contains a small amount of iron oxide, silicon oxide and other components. It is white in color. It is made by smelting at a high temperature of more than 2000 degrees in an electric arc and then cooling. It is crushed and shaped, magnetically separated to remove iron, and screened into a variety of particle sizes. Its texture is dense and hard, and the particles form sharp corners.
