The role of non-ferrous metals and Alloys in Electrical Engineering Industries in particular relation to cable Industries

NON-FERROUS metals in major use in electrical industries are copper, aluminium, silver, cadmium, lead, tin, antimony, zinc, nickel and chromium. Copper, by virtue
of its high conductivity second only to silver, and other excellent properties, has always been the ideal conductor material but it is only recently that its position is being challenged by aluminium due to scarcity of copper in the world market and its wildly fluctuating price. As aluminium is a metal whose source is almost unlimited,
its use is bound to continue to rise as demand on copper grows with increasing industrialisation and urbanisation of the underdeveloped or developing countries and its source gets gradually depleted with increasing off-take.
