Although allied to nickel, it has distinctive differences. It is more
active chemically than nickel. It is dissolved by dilute sulfuric, nitric,

copper alloys is inferior to that of nickel, but small amounts in nickelcopper
alloys will neutralize the yellowish tinge of the nickel and
make them whiter. The metal is diamagnetic like nickel, but has
