Electric conductors are materials that have movable electrically charged particles, known as electrons in metals. Manufacturers use metals for making electrical like brass earthing accessories, copper wires, brass terminals, aluminum plates, etc.
When an electric charge is applied to a metal, the electrons move, which lets electricity to flow through. Materials with high electron mobility considered as good conductors while materials with low electron mobility are called insulators.
Let’s talk about different materials and their conductivity
Silver is known as the best conductor of electricity since it contains a higher amount of mobile atoms. It is must for any material to pass through the electricity to be known as good conductor. But this metal is expensive and is not usually used by manufacturers unless they are making any specialized equipment like circuit boards or satellites.
Copper is less conductive as compared to silver, yet it is widely used in making effective conductor in household appliances. Most wires manufacturers use copper plating and wrap the electromagnet cores with copper wire. Since it is easy to solder copper and wrap into wire, cable and wire industry use this metal in large amount.
Aluminum is more conductive than copper and less costly. Aluminum material is used in household wiring but it has limited usage. The metal has multiple structural flaws. It is rather used for high-voltage transmission lines that can be encased in steel for extra protection.
Gold is a great electrical conductor and doesn’t tarnish when exposed to air. However, it is the precious metal that comes at higher price. Gold is specifically used for materials like circuit board components or small electrical connectors. There are some materials that may get gold plating as an electric conductor.
Steel is an iron alloy, which is also a conductor and highly corrosive. Steel is tough at casting and manufacturers don’t apply it in small products or machines.
Brass is an alloy having good tensile strength. Manufacturers can easily bend the brass into different shapes. As compared to steel, brass is less corrosive, more conductive and cheaper to buy.
Compared to all the materials, brass is the most favorite one for manufacturing units. Even brass earthing accessories makers use this material for their products. You are now aware of the reasons behind their preference.
