Brown fused alumina 

  • HS Code: 281810100

  • Origin: China

Quality at very good price! 

Brown fused alumina is made from high quality bauxite and anthracite etc. By fusing in a tilt-pour or fixed electric arc furnace, processed with cone crusher and barmac crusher by dressing, magnetic-separation and screeing, the crystallized ingot becomes grains of high density and hardness, good self-sharpening and excellent alumina grinding properties. It is suitable for manufacturing vitrified and resinoid tools, lapping, polishing and blasting, also used as superior refractory materials.
