Facts
Interesting Facts
  • It is the most reflective element.
  • Silver is the second most ductile metal after Gold.
  • It is also used in Dentistry as a dental alloys for clips and crowning.
  
  • 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
  • Silver is mainly used for Jewelry and show piece.
  • It is used for manufacturing high quality mirrors due to its reflectivity property.
  
  • 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.
