Brown Fused Alumina 95% Introduction
Brown fused alumina also named emery. The raw materials is bauxite, carbon materials and iron scrap. Put the raw materials into arc furnace, passed the high temperature. The main ingredient is Al2O3 and the content is 75-95%. Also have some other ingredient, such as Ti, Si, Fe. The brown fused alumina is the based material of the abrasive.
Brown Fused Alumina Characteristics
High hardness, high crystallinity, good linear flow performance, weak adherence, no explosion while using, no cracking, no pulverizing, abrasive product with dark blue color after burning, no net cracks, no rust.
