- Wis Efesus banget winates minangka logam beracun lan bisa nimbulaké cacat lair, kanker, etc.
- Meh 80% saka logam kadmium digunakake ing Nikel Baterei kadmium lan saiki lagi njupuk diganti karo isotop nikel.
- Gunakake utama Praseodymium kalebu wesi. Praseodymium -Magnesium alloy digunakake ing mesin pesawat amarga kekuatan dhuwur.
- metal iki uga digunakake nalika nggawe wesi sembrani permanen.
