Ulah lan Wuku
- Nduwe kemampuan kanggo nyerep neutron lan mula digunakake kanggo nggawe rod kontrol ing kapal selam nuklir. Lan logam iki uga digunakake ing obor welding Plasma.
- Iku wesi karo wesi, titanium lan niobium banget migunani.
- Sampeyan uga dipigunakaké ing insecticides, alami rambute lan minangka aditif anti-nuthuk kanggo bensin. Nanging kabeh iki dilarang déning pamaréntah minangka logam Lead dikenal kanggo ngrugekake kanggo kesehatan.
