棕刚玉16# Brown Fused Alumina从高品位的煅烧铝矾土冶炼而来。在国标标准中，只对一级棕刚玉的技术标准进行了要求。一级次、二级、三级棕刚玉并没有特定的规范。一级棕刚玉16#具有良好的研磨硬度和韧性，不仅适合金属、碳钢、不锈钢的研磨，也可以作为耐磨骨料添加于地坪或用于耐火骨料。
Brown Fused Alumina 16 # is smelted from high-grade calcined bauxite. In the GB/ISO standard, only the technical standard for A grade Brown Fused Alumina is required. There are no specific specifications for B grade,C grade and lower quality brown one. A grade brown fused alumina 16 # has good grinding hardness and toughness, which is not only suitable for grinding metals, carbon steel, and stainless steel, but can also be added as wear-resistant aggregates to floors or used as refractory aggregates.
