White corundum is produces from high-quality aluminum oxide. The colour is pure white. It has high hardness, toughness slightly lower, high-purity. As high-level abrasives, it applies to a wide range of precision casting, steel fire-resistant, fire-resistant chemicals, 95 electrical porcelain, decorative porcelain and so on with daily life and special ceramic porcelain, as well as the military industry, electronics and other high-tech industry.
We are mainly exporting white fused alumina products to Asia, Europe and United States. We are preparing to provide high quality and satisfactory service for you.
