白剛玉是以優質鋁氧粉原料,經電熔提煉結晶而成,它的硬度略高于棕剛玉,韌性稍低、純度高、自銳性好、磨削能力強、發熱量小、效率高、耐酸堿腐蝕、耐高溫、熱穩定性好。其磨具適用于磨削高碳鋼、高速鋼等細粒度磨料。白玉剛段砂還可以用于精密鑄造高級耐火材料。
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.
