棕刚玉180#Brown Fused Alumina由一级棕刚玉经破碎、球磨、筛分、磁选而来。它具有棕刚玉一级砂的高硬度、高韧性等特点。棕刚玉F180符合欧标FEPA标准，金属杂质少，金属的研磨减少铁残留，性价比高于白刚玉。
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.
