Bronze

Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc)

Taking into consideration its main element of alloy, it is common to divide bronze into two groups:

  • Bronze with tin
  • Bronze without tin- it consists of other metals (such as aluminium) and non-metals or metalloids (such as arsenic, phosphorus or silicon).

  • Bronzes are typically very ductile alloys, considerably less brittle than cast iron. Usually two times more expensive than brass. Other additional elements make alloy that has better physical, mechanical, and chemical properties.
