DURA-52 复合氧化锆珠(ATZ)是由钇稳定的氧化锆和氧化铝微粉经精磨，干燥后滚动成形。均一的微晶结构给珠子带来理想的耐压强度和耐磨性。相对于钇稳定的四方氧化锆珠，虽然密度稍有降低，但价格便宜为其加分不少，大部分场合能代替四方氧化锆珠，匹配的砂磨机线速度可达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.
