Light metal

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A light metal is any metal of relatively low density.[1] More specific definitions have been proposed; none have obtained widespread acceptance. Magnesium, aluminium and titanium are light metals of significant commercial importance.[2] 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,[3] iron (7.9) and copper (8.9).
