Copper bars are widely used in shipbuilding, military, automobile and communication industries. The components in these industries need good wear resistance and corrosion resistance.

The microstructure of copper base corrosion resistant alloy should be single-phase to avoid electrochemical corrosion caused by the second phase in the alloy. For this reason, the added alloy elements should have great solid solubility in copper bars, even infinitely miscible elements. Single phase brass bars, bronze bars and white copper bars used in engineering have excellent corrosion resistance and are important heat exchange materials.
