白刚玉是以优质铝氧粉原料,经电熔提炼结晶而成,它的硬度略高于棕刚玉,韧性稍低、纯度高、自锐性好、磨削能力强、发热量小、效率高、耐酸碱腐蚀、耐高温、热稳定性好。其磨具适用于磨削高碳钢、高速钢等细粒度磨料。白玉刚段砂还可以用于精密铸造高级耐火材料。
WHITE CORUNDUM
White corundum is made from high-quality alumina powder material by electric melting, refining and crystallizing. lts hardness is a lttle higher than brown corundum with the feature of lower toughness, high purity, good self-sharpening, well grinding, little calorific power, effective efficiency, acid corrosion, high temperature resistance and good thermal stability. Its grinding tools are suitable to cut and grind high carbon steel, high speed steel and stainless steel. White corundum sand can also be used for precision casting and high-refractory materials.
