Copper Alloy
Copper alloys are metal alloys that have copper as their principal compoenet. They have high resistance against corosion. Bronze is created when tin is added, Brass is created when zinc is added. It is almost impossible to separate the different alloys based on appearance alone. Chemical testing is needed to distinguish these separate alloys.
