噴砂用棕剛玉
棕剛玉，也稱為棕剛玉或 BFA，是透過電弧爐製程生產的。棕剛玉是一種堅硬（莫氏硬度 9）且堅韌的高強度材料，使其成為噴砂介質、砂紙、砂輪以及研磨盤、輥、帶和墊等應用的優質磨粒原料。其熱性能也使其成為耐火材料應用的優質原料。
由於棕剛玉具有高堆積密度和高硬度，使其成為去除鐵鏽、氧化皮和表面污染物的完美介質。一致的顆粒尺寸可實現均勻的表面光潔度和覆蓋範圍。
此外，BFA 的脆碎度較低，平均可再循環七次。這些特性減少了磨料消耗、清理和處置成本，從而提高了獲利能力。
1 .棕剛玉的特徵是純度高、質地緻密、堆積密度大、自銳性強、韌性好、磁性含量極低；
2.用其製成的磨俱具有磨削鋒利、加熱速率低、磨削比高、使用中粘附少等優點；
3.燒結磨俱燒成後具有顏色深藍色、無網狀裂紋、無鏽斑的特性。
