产品属性
星光耐材 厂家*黑刚玉 各种规格黑刚玉/****黑刚玉
黑刚玉是以****的铝矾土为主原料，经电弧炉精练而成。而后经过完整的科学加工程序进行加工，铝含量大于80%。产品硬度适中，韧性较大*棱角锋利，自锐性强，抛光加工工件洁度高，其抛光性能大大高于国内外其他同类产品，广泛应用于餐具行业，电镀行业，金属表面处理行业，玻璃制品行业，目前，****为广泛地应用于不锈钢餐厨具，灯具灯饰摩托车零件，汽车配件等中等硬度材料的精细抛光，其抛光的各种性能、效果可于日本黑刚玉砂相媲美。目前，是公认的国内****替代是用国外黑刚玉砂进口材料的黑刚玉抛光
Black corundum
Black corundum is also known as low aluminum corundum. It is also a new type product of polishing material, and it is a dark gray crystal body made α-Al2O3 and ferropicotite a*ain ore in the electric arc furnace by *elting the bauxite. It has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability. It i*ainly suitable for free grinding, such as coarse grinding before electroplating product*ainly for polishing and sandblasting of stainless steel, fabricated metal products.
