Which Metals Best Conduct Electricity?
Metallic bonding causes metals to conduct electricity. During a metallic bond, the metal’s atoms are surrounded and constantly moving through a sea of electrons, which enables the metal to conduct electricity and move freely with ions. All metals perform differently, which means some are more conductive than others.
Electric Conductive Metals
We have listed some of the best and most compelling conductors of electricity below, along with an explanation!
Silver
Silver is considered the best metal conductor of electricity because it contains the highest amount of moveable atoms. For a metal to be a good conductor, the electricity passed through must be able to move electrons, so the more electrons, the higher conductivity.
Copper
Copper is considered to be less conductive than silver but is relatively cheaper and is more commonly used in household appliances. For instance, most wires are copper-plated, and electromagnet cores are usually wrapped with copper wire. Overall, copper is used when large amounts of conductive material are needed or required.
Aluminum
Aluminum is a great conductor of electricity but not as great as copper. It creates an electrically resistant oxide surface in electrical connections, which can overheat. Encased steel high-voltage transmission lines tend to use aluminum as well.
Brass
Brass is an alloy and tensile metal used in smaller machines due to its flexibility and ability to be maneuvered into different parts. It’s considered to be better than steel because it’s more conductive, cheaper, less corrosive, and maintains its value after use.
Platinum
Platinum has high electrical conductivity and is more ductile than gold, silver, and copper. A few fun facts about platinum are that it has excellent corrosion resistance, is stable at high temperatures, and has very stable electrical properties.
Steel
Steel is an alloy of iron and a conductor of electricity. It is usually powered to encase other types of conductors because it is inflexible and highly corrosive when exposed to the air.
What Factors Affect Electrical Conductivity?
Several factors impact how well a metal conducts electricity! Check them out below!
- Temperature: Increasing temperatures create a thermal excitation of atoms and can decrease conductivity while increasing resistivity.
- Structure & Phases: Conductivity will slightly slow down if there are different phases of materials within a metal. Its overall process can have a lasting effect on its conductivity.
- Frequency: High frequencies cause current flow around conductors rather than through them. If there are no frequencies, the direct current will not be affected.
