More Information
Summary:There is provided a copper-base alloy useful for coinage that has a golden visual appearance. The material has a transverse electrical conductivity substantially similar to that of copper alloy C713 and when clad to a copper alloy C110 core, a transverse electrical conductivity substantially similar to both sides of a Susan B. Anthony United States dollar coin. The copper-base alloy is a copper-manganese-zinc-nickel alloy.
