DURA-52 復(fù)合氧化鋯珠(ATZ)是由釔穩(wěn)定的氧化鋯和氧化鋁微粉經(jīng)精磨，干燥后滾動(dòng)成形。均一的微晶結(jié)構(gòu)給珠子帶來理想的耐壓強(qiáng)度和耐磨性。相對(duì)于釔穩(wěn)定的四方氧化鋯珠，雖然密度稍有降低，但價(jià)格便宜為其加分不少，大部分場(chǎng)合能代替四方氧化鋯珠，匹配的砂磨機(jī)線速度可達(dá)14米/秒。DURA-52 Alumina Toughened Zirconia (ATZ) bead was granulated from the ultra fine zirconium dioxide and alumina powder. The consistent micro poly-crystal benefits high compressive strength and wear resistance of beads. Although there is a lower density than T-TZP (Yttria-Tetragonal Zirconia Polycristal), the lower unit cost is an obvious plus. It can replace it in more application and is competent the mills with high tip speed up to 14m/s.密度Specific Gravity： 5.2kg/dm3堆積密度Bulk Density： 3.2-3.4kg/L微觀硬度Micro Hardness： 1100kg/mm2抗壓強(qiáng)度Compressive Strength： 180kgf(2mm)粒徑Sizes： 0.6-3.5mm包裝Packing： 25kg/桶
