Abstract
Many important applications of copper require a combination of properties that fall into the following two classes: (A) strength and conductivity, and (B) colour and corrosion resistance. This review discusses the metallurgical factors of importance for these combinations of properties. The possibilities for high-strength, high-conductivity copper alloys are discussed first. Colour and atmospheric corrosion resistance is the second theme. An outline is also presented on the new metallurgical directions that are opening up due to the various processing possibilities inherent in rapid solidification.
