As one of the main manufacturers and exporters for abrasive, refractory materials and metallurgy industry in China. We have six plants (Two Fused Plant ,Three processing Factories, One Special Refractory material plant,One metallurgy material Plant,One Acid washing and Water washing plant, and Sales Department ).We can produce 80,000 tons annually. Our products include Brown Fused Alumina95%, Brown Fused Alumina98%,White Fused Alumina, Black Fused Alumina, Compact Fused Alumina, Semi-Friable Fused Alumina, Micro Crystalline Fused Alumina, Calcium Aluminate etc. We have passed ISO9001-2000 Quality Management System Certificate.
White fused alumina is electrically fused in arc furnace with high grade Bayer''''s process alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. Abrasives tools made of it are suitable for grinding high-speed, high carbon steel, etc. It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc.
