Copper, brass, and bronze are all relatively immune to saltwater corrosion. Brass artifacts of all sorts are easily cleaned up into shiny souvenirs for those who value them. Bright green copper sheets and tubes add color to many wrecks, while bronze is the material of choice for the most coveted of all diver's artifacts - a ship's bell.

Copper and some of its alloys have been used by humanity since the Bronze Age. One of the first metals known to humans, free copper was probably mined in the Tigris-Euphrates valley as long ago as the 5th century BC. Cyprus, from which the metal's name originally comes, was the primary source of copper in the ancient world.
