Brown Fused Alumina
Brown Fused Alumina is fusing under the high temperature of above 2250°C with high quality abrasive bauxite as raw material. It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can produce ceramic grinding wheel ,resinoid grinding wheel. And BFA could be used for abrasive、sandblasting and precision casting.
In order to meet the demands of the refractory industry, we independently develop and produce brown fused alumina. Which is characterized by high purity,good crystal,strong fluidity,low coefficient of linear expansion,good corrosion-resistance and so on. RS Brown fused alumina could not burst、pulverise and craze in using course.
