Wires are an important part of the household and

Copper clad steel also referred to as copper covered steel is a bi-metallic product known for its high resistance of steel, conductivity and can avoid corrosion to a great extent. Copper clad steel has maximum application in the wire industry. It is the basic component used in grounding in homes, companies, factories etc. The other copper conductors can be used instead of copper clad steel but clad's tensile strength makes it better than the rest. All over the world it has been installed for the purpose of grounding and has witnessed a life span of over 60 years. The tensile strength of copper clad steel makes it an appropriate prop for various purposes. It also has a resistance against material fatigue which prevents progressive and localised damage of the structure. Installations with this are generally a good ground. The inseparable metallic compounds in it are helpful. It also has a smaller diameter which marks its applicable in c0-axial cables. Copper clad aluminium, commonly also known as cca wires, has an outer copper cladding like copper clad steel but it has an inner aluminium core. This bi-metallic product has the favourable properties of both the metals. In terms of weight it is lighter than pure copper and in terms conductivity it has a higher electrical conductivity as compared to pure aluminium. The basic application of cca wire is in voice coils for headphones. It is also used in portable loud speakers and mobile coils. Copper clad aluminium is preferred over pure copper wire due to its efficiency as well as cheaper rates. Copper clad aluminium has a skin effect that causes alternate current to be focussed on the more copper cladded areas of the wire that causes the resistance of the wire to approach the resistance of pure copper wire. The same skin effect is also displayed by copper clad steel as well. It is also used in mains cable for domestic as well as commercial purposes. Wires are an important part of every infrastructure. It is required in the most important spheres of work. It has a great contribution in the transmitting oriented services like in communication. The property of wires which enables them to transmit alternating current is a discovery that has helped man to achieve the best of devices. The discovery of bi-metallic wires like copper clad steel has a scope of further improvement.
