Why Copper Is The Best Choice For Electrical Connectors?

Copper Wire

The most economically feasible components of contemporary engineering equipment and machinery are bare copper wires. Every electrical device, from electric kettles to massive blast furnaces, has bare copper in some form. Copper, with its exceptional physical and electromagnetic qualities, is regarded as a fundamental element in altering electrical science. Copper may now be found in almost every aspect of life.

To for an electrical current to pass through metals, the power source must overcome resistance. The resistance of a metal is related to its electrical conductivity. Because of its low resistance, copper wire is a good electrical conductor.

Copper Wire is a material that may be used in a variety of ways. Most metals can’t bend easily, therefore electrical connections and wiring must transmit large quantities of electricity at once. Copper, on the other hand, is the ideal thickness for working with house electrical while on the go.

Finally, copper oxidises at a slower pace than other metals. You’ve probably heard about oxidation when it comes to rust. It happens when airborne oxygen and moisture react with a metal’s surface.

This process causes the metal to corrode, resulting in a film-like coating.

Copper does not rust but does develop a greenish patina known as copper oxide. This covering, unlike rust, protects the metal from corrosion while not interfering with conductivity.


While aluminum may be utilized for all electrical applications, copper has the advantage for various reasons.

For starters, aluminum has a lesser conductivity and is more prone to oxidation than copper. The aluminum oxide that develops on the surface is not as conductive as copper oxide, slowing the passage of energy. Aluminum requires anti-oxidant cream to flow properly in order to battle oxidation.

When comparing aluminum and copper electrical connections, it’s also important to think about safety. Because metal expands and contracts as it heats and cools, it may loosen over time, posing a serious fire threat.

While these safety concerns may be addressed, they will necessitate particular attention. Unique fittings that compliment aluminum wiring, Arc Fault Interrupters, and “pig-tailing” copper wire at the ends of aluminum wires are just a few examples. Copper wiring, on the other hand, is far safer and needs less measures.

Copper is a far superior material for electrical wiring in compact locations because of these characteristics. It’s just a superior choice because of the metal’s flexibility, resistance to heat expansion, and general safety factors.
