  • Innovations in Copper: Electrical and Metallurgy of Copper

    IntroductionApplications of High Copper AlloysAlloy DevelopmentForms AvailableHardening of CopperCastingMachiningHeat TreatmentElectrical Conductivity/ResistivityLinksPure copper has the highest electrical conductivity of any commercial metal. This property makes it the preferred material for power and telecommunications cables, magnet (winding) wire, printed circuit board conductors and a host of other electrical applications. Copper has sufficient strength, ductility and hardness for these applications at operating temperatures up to 210 F (100 C). For many other applications, however, the demands of electrical technology require copper to have higher mechanical properties and to be capable of use at elevated operating temperatures while still retaining the good conductivity for which it is selected in the first place. The copper industry has invested much research effort over the years to create materials capable of meeting these demanding needs. The products of this research are found in the large variety of high copper alloys, materials whose properties are equal to or, in some cases, higher than those of many other engineering metals, yet,...
