Uses
Uses & Benefits
  • Currently known uses of Ununtrium metal are limited to research purpose only.
  
  • This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
  • Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
