棕剛玉30#Brown Fused Alumina的特點(diǎn)和用途

       棕剛玉30#Brown Fused Alumina是一種硬度高,韌性好的氧化鋁研磨材料。它是將煅燒鋁礬土進(jìn)行高溫熔融再凝固后得到的人造磨料。一級棕剛玉氧化鋁含量為94-95%,硅鐵含量低,適用于高速切割、打磨、干式、濕式噴砂等應用。
       
Brown Fused Alumina 30 # is an alumina grinding material with high hardness and good toughness. It is an artificial abrasive obtained by high-temperature melting and solidification of calcined bauxite. The content of primary brown fused alumina is 94-95%, with low silicon iron content. It is suitable for high-speed cutting, polishing, dry, wet sandblasting and other applications.
