3 Facts

3.1 Interesting Facts

Platinum is the rarest metal from the Precious metal categories..
Commercially Platinum is produced as a byproduct in ores of nickel.

Manganese is an essential trace element in all forms of life.
Manganese metal oxidizes very easily, but it does not fuse that easily.

5 Uses

5.1 Uses & Benefits

Platinum metal is mainly used in jewellery.
Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.

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.
