Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion.The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both of these are imprecise terms, having both been commonly referred to as lattens in the past. Today the term copper alloy tends to be substituted, especially
