Over the past 18 years, TAOANG products range from raw material bauxite to processing follow-up products brown fused alumina, finishing white fused alumina and dense fused alumina, bubble alumina, and fused alumina micro powder. The production process is fully controlled to achieve control of product quality and price.
Brown fused Alumina is an artificial corundum, which is made of bauxite, carbon materials and iron fillings melted and reduced in an electric furnace. The main chemical composition of brown fused Alumina is 94.5%-97% AL2O3, and it also contains a small amount of iron, silicon and titanium, etc. White fused Alumina is made from industrial alumina powder that is melted in an electric-arc furnance at high temperature over 2000 degrees and then cooled. It is crushed and molded, then iron is removed by magnetic separation and sifted to various particle sizes. It has dense texture, high hardness and sharp angle of the grits. The difference between white fused Alumina and brown: 1, Different composition:White fused alumina: alumina content of 99.4%, mohs hardness of 9.0.Brown fused alumina: alumina content of 95%, mohs hardness of 8.9. 2, Different color:White fused alumina: white and transparent, mostly white.Brown fused alumina: dark-brown, brownish red. 3, Different purpose:White fused alumina: mainly used in high-end industries. It has a strong cutting force, used to remove burrs of metal or non-metal, has a polishing effect for the surface of parts, belongs to the medium polishing abrasive.Brown fused alumina: More popular and it is used to remove burrs on the surface of stainless steel, carbon steel and aluminum alloy 4, Different smelting methods:White fused alumina: made from high quality alumina powder. Have features of high purity, good sharpness, acid and alkali resistance, corrosion resistance, high temperature resistance, thermal stability.Brown fused alumina: made of bauxite, carbon materials and iron fillings melted and reduced in an electric furnace. It is brown and with good toughness.
