Copper wires are as popular as aluminium wires. However, aluminium wires score over copper ones when it comes to their costs. Aluminium being inexpensive compared to copper scores over the latter. Nevertheless copper wiring holds its own with its distinct advantages over aluminium.

Characteristics of copper wires

Ductility of copper allows its extensive usage in power cord manufacturing especially in making extremely thin wires. This is not possible with aluminium. Due to its thin size, copper wire is preferred over aluminium when ducts are smaller. High ductility of the metal also makes copper wires safer than aluminium wires.

Tenacity of copper is another property due to which this metal is a preferred choice for wiring for various industrial sectors. It can withstand extreme pressure. Aluminium deforms easily, so extra clamps are used to secure the wires, which come with added risk of getting loose over time. Copper can withstand corrosion much better than aluminium. This characteristic of the metal makes copper wires more durable than aluminium ones.

To protect aluminium wires from corrosion, they are coated with antioxidant solutions or pastes whereas copper wires do not require the special treatment. For this purpose, mechanical efforts are also sometimes used during aluminium wire installation. However, due to growing incidences of aluminium wires catching fire, theirĀ  usage has became less and copper wires are becoming the preferred wire choice, especially for residential use.

Benefits

High electrical conductivity is another property of copper due to which it is in high demand despite its higher cost than aluminium. There are only a few other metals, which can conduct electricity as well as copper does. It is used for wiring across all sectors; whether industrial or residential. High electrical conductivity also makes soldering process of the copper wiring much easier. Also, owning to this quality of the metal, wires made from copper are far more energy-efficient than aluminium ones.

Easy installation of copper wiring scores the metal over others, especially aluminium. Copper wires have a smaller cross-section than aluminium wires and so are easier to use for different applications. Aluminium wires on the other hand, have larger cross-sections, which render them less effective than copper wires.

Thermal conductivity of copper is also another advantage of the wire making it fit for power cord manufacturing. It makes copper wires more efficient for industrial use than aluminium wiring. Copper wires can be safely used for high voltage to low voltage equipment with the same ease.
