Facts
Interesting Facts
  • It is found in copper ores and from the crust of the earth.
  • It is the most malleable and ductile metal.
  • Gold alloys are used in Dentistry as fillings, crowning, clips, etc. It is also used as an artificial limb joints.
  
  • Manganese is an essential trace element in all forms of life.
  • Manganese metal oxidizes very easily, but it does not fuse that easily.

Uses
Uses & Benefits
  • Gold metal is mainly used for Jewelry, bullion, coinage, etc.
  • It is used in the art, decoration, ornaments, etc. It is also used for electroplating process.
  
  • 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.
