喷砂黑刚玉
黑刚玉是于电弧炉中，将铝矾土熔炼而制得的一种以a-AL2O3和铁尖晶石为主矿相的灰黑色结晶体，具有韧性高、耐高温、热太性能稳定的特点。硬度適中，韌性較大，*，棱角鋒利，自銳性強，拋光加工工件潔度高，廣泛適應於食具行*，*鍍行*，金屬表面*理行*，玻璃*品行*，目前，****為廣泛地應用於不鏽剛餐廚具，燈具燈飾摩托車零件，汽車配件等中等硬度材料的精細拋光。
Black corundum is in the electric arc furnace in the *elting and bauxite obtained an order to a-AL2O3 and iron ore spinel phase mainly gray and black crystals with high toughness, high temperature, stable performance characteristics of heat too.Hardness, toughness greater wear, sharp edges and corners, from the sharp and strong, clean and high polished workpiece is widely adapted utensils industry, electroplating industry, metal surface treatment industry, glass industry, currently the most widely usedtableware and kitchenware in stainless steel just, lamps lighting motorcycle parts, auto parts and other medium hardnes*aterials, fine polishing.
