PrAl2Zn2
metal· JVASP-16674· PrAl2Zn2
PrAl2Zn2 is an intermetallic compound combining praseodymium (a rare-earth element), aluminum, and zinc—a research-phase material not yet widely deployed in commercial production. This ternary intermetallic belongs to the family of lightweight rare-earth aluminum alloys being investigated for applications requiring high specific stiffness and thermal stability at elevated temperatures. The material remains primarily in academic and exploratory development stages, where researchers assess its potential as an alternative to conventional aluminum alloys and titanium alloys in weight-critical aerospace and automotive subsystems.
