棕剛玉180#Brown Fused Alumina由一級棕剛玉經(jīng)破碎、球磨、篩分、磁選而來。它具有棕剛玉一級砂的高硬度、高韌性等特點。棕剛玉F180符合歐標FEPA標準，金屬雜質少，金屬的研磨減少鐵殘留，性價比高于白剛玉。
Brown Fused Alumina 180 # is made from primary brown corundum through crushing, ball milling, screening, and magnetic separation. It has the characteristics of high hardness and high toughness of brown corundum first grade sand. Brown corundum F180 meets the European FEPA standard, with fewer metal impurities and reduced iron residue during metal grinding, making it more cost-effective than white corundum.
