DISCRIPTION
The white aluminum oxide, also known as white fused alumina, white corundum, is made of industrial aluminum powder as raw material, smelting at a high temperature of 2000 degrees or more in an electric arc furnace, and is cooled, pulverized, shaped, magnetic materials removed, and sieved into various grain sizes. It has the characteristics of dense texture, high hardness, high bulk density, low porosity, iron-free and good thermal shock resistance, is high quality blasting abrasive, especially suitable for sandblasting operations where iron residue is strictly prohibited. Micro-powder grade is very suitable for wet blasting and grinding. It is suitable for super-fine grinding and polishing of crystal and electronics industries.
