Light metal

A light metal is any metal of relatively low density.Jackson JA, Mehl JP, Neuendorf KKE (eds) 2005, Glossary of Geology, 5th ed., American Geological Institute, Alexandria, ISBN 0-922152-76-4, p. 371 More specific definitions have been proposed; none have obtained widespread acceptance. , and are light metals of significant commercial importance.Brandes EA & Brook GB (eds) 1998, Light Metals Handbook, Butterworth Heinemann, Oxford, ISBN 0-7506-3625-4, p. viii Their densities of 1.7, 2.7 and 4.5 g/cm3 range from 19 to 56% of the densities of the older structural metals,Polmear I 2006, Light Alloys: From Traditional Alloys to Nanocrystals, 4th ed., Butterworth Heinemann, Oxford, ISBN 0-7506-6371-5, p. 1 (7.9) and (8.9).
