Birta Praseodymium, waxa loo istcimaalaa sida walaxda awood sare leh ee Magnesium-ka loo isticmaalo qaybo ka mid ah matoorada diyaaradaha. Waa wakiilka alloying ee muhiimka ah ee Neodymium-Iron-Boron magnets. Praseodymium waxaa loo isticmaalaa in lagu abuuro birlab awood sare leh oo caan ku ah xooggooda iyo cimrigooda. Waxa kale oo loo istcimaali jiray shilalka, shuclada, dab-damiska 'dhagaxa iyo birta', iwm. Birta Praseodymium waxa lagu sii farsamayn karaa qaabab kala duwan oo ah jeexjeexyada, googo'a, fiilooyinka, foils, sabbooyin, ulo, saxanno iyo budo.
