China 1-3mm Top Quality White Fused Alumina for Refractory Industry, Find details about China White Corundum, White Fused Alumina Oxide from 1-3mm Top Quality White Fused Alumina for Refractory Industry
White fused alumina is electrically fused in arc furnace with high-grade aluminum oxide powder as raw
material. Compared with brown fused alumina, it is of higher hardness and slight lower toughness. It is
also characterized by its high purity, ability of self-sharpening, high cutting rate, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As abrasive material, it is widely used for bonded and coated abrasive, polishing, precision casting and so on.
White Fused Alumina Application:
1.White corundum for refractory material
2.White corundum for Abrasive
3.White corundum for Sand blasting
4.White corundum for precision casting
