3 Uses

3.1 Uses & Benefits

Europium metals main uses is in the printing of euro banknotes. These notes glow red under UV light.
It is used in low energy light bulbs.

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.
