Ulah lan Wuku
- Ora ana panggunaan komersial, nanging paduane akeh dikarepake. Lanthanum lan Nikel alloy digunakake kanggo panyimpenan gas hidrogen.
- Panggunaan paling misuwur kanggo campuran mischmetal saka Lanthanum yaiku; minangka 'flints' kanggo korek rokok.
- Plutonium iki digunakake ing bom atom lan isih digunakake ing macem-macem senjata lan industri amunisi.
- Sampeyan uga dipigunakaké ing tanduran daya nuklir minangka sumber energi kanggo papan misi.
