The Metallurgy of Copper Wire by Dr. Horace Pops Essex Group, Inc. Introduction Copper is the preferred and predominant choice in the electrical industry because of its high conductivity, both electrical and thermal. In order to obtain the required properties, unalloyed high purity copper is almost always used. This article discusses the rationale for this choice, and pays particular attention to the underlying metallurgical principles. It is intended to serve as a technical discussion of pertinent developments spanning the past several decades in the copper wire industry. Conductor Requirements Considerable progress has been made in recent years to explain the electronic nature of the noble metals, i.e., copper, silver, and gold. These elements exhibit high conductivity because their conduction electrons show relatively little resistance to movement under an electric field. Copper in particular is an excellent conductor because outermost electrons have a large mean free path (about 100 atomic spacings) between collisions. The electrical resistivity is inversely related to this mean free path. Several electrically conductive metals are lighter than copper, but since they would require larger cross-sections to carry the same current, are unacceptable if limited space is a major requirement (e.g., in small electric motors). Consequently, aluminum is used mainly when excessive weight could become a problem. Copper possesses the best characteristics for commercial applications, inasmuch as silver must be dismissed because of its prohibitively high cost.

Prospective students Student information Alumni and friends Faculty and staff ... Contacts Highlights: Our undergraduate programs are structured as a CO-OP programs, promising work experience and high employability to our graduates. In terms of graduate students, the Department has the best program in Canada in the respective fields of mining and metallurgical engineering. The department has one of the highest research funding levels per professor of all Faculties of Engineering in all disciplines across Canada. The Department's two separate undergraduate programs are (subject to University approval): Mining Engineering Materials Engineering. Chair's welcome message Dr Robin A.L. Drew As Chair of McGill's Department of Mining, Metals and Materials Engineering, I wish to welcome you on behalf of the faculty, staff and students to our web site. I hope you find the information on both the undergraduate and graduate programs useful and informative. I encourage you to browse the pages and become familiar with the Department's teaching activities as well as the various research areas.

La roche qui compose notre planète est en fait l'unique source de minéraux dont l'homme dispose. C'est par l'union des efforts des ingénieurs des mines et de la métallurgie que nous pouvons extraire, de la roche qui nous apparaît sans valeur, tous les métaux précieux (or, argent, etc..) et de base (cuivre, zinc, etc..) du tableau périodique. L'obtention d'un métal ou d'un matériau de haute technologie passe par trois étapes clés: l'extraction du minerai, son traitement pour produire le métal et sa mise en forme pour en permettre l'utilisation dans notre vie courante.
