Top 5 Reasons Why Copper Wires Are Used As Electrical and Mechanical Wires

Posted on Dec 11, 2014

The bare copper wires are the most commercially viable components of the modern day engineering instruments and machines. From electric kettle to gigantic blast furnaces, every electrical gadget has bare copper somewhere or the other. Considered as the key element in transforming the electrical science with its superior physical and electromagnetic properties, copper today has entered almost every aspect of the life. The bare copper wires are the most conventional forms of engineering wires that can be used in repairing and replacing the faulty electric lines.
The top 5 reasons why bare copper wires are used as electrical and mechanical wires are as follows.

1. High electrical conductivity:

The bare copper wires retain the best electrical properties that noble metals exhibit in the nature. Apart from the superior electrical conductivity, the bare copper wires also boost transmission through them by offering minimum resistance.
The electrical conductivity ensures that the bare copper wire can be used in circuits and overhead power transmission lines. They are used in automobiles, heavy machineries and industrial Transformers and submarines.

2. Superior magnetic properties

The bare copper wires exhibit relatively stronger magnetic properties than other naturally occurring metals. It can be used to make solenoids and magnetic bars. Most instruments have copper, and the bare copper wires ensure that the electrical properties of the component are not affected by the magnetic straying. Most elements have issues related to the intermingling of both properties.
The bare copper wires are used in magnetic compasses, ship navigation systems, airplane cockpit systems and radio frequency catchments antennae.

3. Durability

No electrical wire component can beat the durability features offered by the bare copper wires. Due to their long-lasting properties and impressive resistance against wear and tear, bare copper wires are widely used in fast moving machines and appliances where they constantly have to operate under high temperatures and vibrations.
The bare copper wires can withstand the strain for much longer duration than the conventional wires. The property of durability makes the copper wire to be used for applications in places where the machines are subjected to corrosion, chemical reactions and atmospheric abrasion due to moisture, salinity and grease.

4. Ductility

The bare copper wires have an amazing ductility that makes them favourite for use in smaller machines that have a limitation of space and utility. Owing to the property of ductility, the copper bare wires can be drawn into thin wires with minimum diameters. This engineering property blessed with physical features ensures that the strain in diameter does not result in any change in the electrical properties.

5. Alloyoptions

The bare copper can be alloyed and coated with other metals as well. Nickel, zinc and tin are the most popular metals that are alloyed with bare copper wires to further raise its electrical properties and ensure noncorrosive environment. The electroplating alloys ensure that the bare copper wires remain chemically insulated against environment and abrasive agents. The bare copper wires can also be insulated with adequate external coating for further protection against wear and tear.
