Product Detailed
Hongtai White fused alumina for 1.AL2O3: 99.5% min 2.high function of white alumina 3.high purity fused alumina

White Fused Alumina ( WFA OR WA) is made from chemical by high furnace or tilting furnace at high temperature .

White corundum is based on high-quality aluminum oxide as raw materials, smelting fused together, it has a pure white color, hardness, toughness slightly lower, high-purity, since sharp distinctions, grinding power, heat a small, efficient , Acid corrosion, high temperature, better thermal stability, and other characteristics, it is not only the high-level materials, abrasives, and high-level or grinding, polishing, and other materials, it made the process Grinding, grinding apply to high-carbon steel , A variety of high-speed steel and stainless steel. It also 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. Our company exporting white fused alumina products to Japan, Korea, Europe and the United States and other countries and regions all the year round. We can provide to users a variety of  sub-standard white sand corundum, F Sand, P sand, powder and so on according to the needs of them.
