What is the difference between white fused alumina and brown fused alumina?
1. Different raw materials: The raw material of brown corundum is bauxite. The raw material of white corundum is alumina powder.
2. Different applications: Brown corundum can be used to make ceramics, resin high-consolidation abrasive tools, grinding, polishing, sandblasting, precision casting, etc., and can also be used to make high-grade refractory materials. White corundum is suitable for grinding fine-grained abrasives such as high-carbon steel, high-speed steel and stainless steel. White corundum can also be used for precision casting and advanced refractory materials.
3. The Chemical specification is different: Although both brown fused alumina and white fused alumina contain alumina, the alumina content of white fused alumina is more than 99%, and that of brown fused alumina is about 95%.
4. Different colors: Since the content of alumina in white fused alumina is higher than that of brown fused alumina, the color of white fused alumina is white while that of brown fused alumina is brown-black.
