Ulah lan Wuku
- Iridium duwe sifat anti karat lan digunakake ing alloy khusus karo logam Osmium lan alloy sing digunakake ing tips pen lan Compass bantalan poros.
- Logam rhodium utamane digunakake ing konverter katalitik kanggo mobil amarga nyuda oksida nitrogen ing gas buang.
- Iki digunakake minangka katalis industri kanggo asam nitrat, asam asetat, reaksi hidrogenasi, lsp.
