High Hardness Temperature Brown Fused Alumina for Abrasive
Brown fused alumina (BFA) is electrically fused in an arc furnace from a mixture of BAUXITE,coke as main raw materials at high temperature.it is widely used as abrasive,ceramic,refractory and chemical industry.for refractory application it is used in refractory castable and refractory bricks,while for abrasive application,it is suitable for grinding high-tensile strength metal such as steel,annealed malleable iron etc.
Features and advantages of our brown fused corundum (BFA):
1)high hardness
2)high tension
3)good self-sharpening
4)good thermal stability
5) high temperature resistance
6) anti-corrosion
7)stable chemical properties
