How Does Electroplating Improve Conductivity of Some Metals?

Some metals, despite having exceptional conductive properties, are very resistant to corrosion. External agents such as air and water can trigger natural oxidation process. Rust affects conductivity of certain materials, making them less efficient to perform certain purposes. For example, when we talk about electrical connectors, metal parts must be kept free of rust to have the highest possible conductivity.

Conductivity is the property of materials that defines their ability to conduct electric current. The higher the conductivity value, the less current is lost during its passage through the surface of the material.

Gold and silver, besides being precious metals, have many uses in electrical industry. They are usually used for the manufacture of luxury products such as jewelry and cutlery. However, a small part of the world’s gold and silver is used for plating metal pieces.

Although in world market, value of gold is much higher than silver, in terms of conductivity, silver is more valuable than gold. Silver is the best electrical conductor after graphene, with a conductivity of 6.3 X 10^7 Siemens per meter. Another outstanding quality of silver and gold is that they are both noble metals.

So far, 16 noble metals have been identified in periodic table. Noble metals are those that are chemically inert to effects of external agents, which makes them little susceptible to oxidation. For that reason, if you want to protect a delicate piece of metal from corrosion, silver plating services are the best way to do it.

Silver plating services are usually used to protect metals from corrosion and wear, giving them a much stronger surface. Others only use silver plating for aesthetic purposes, for the silver and shiny finish that remains in metal parts. Electroplating service is always an excellent way to save money.

During the passage of electrical current through a conductor, it’s demonstrated that electrons travel through its surface. For that reason, for a cable to have a good conductivity, it isn’t necessary to be entirely manufactured with a noble metal to have an optimum conductivity. In fact, it’s only necessary that conductor’s surface to be of a highly conductive material.

Electroplating service is the best way to improve conductivity of cables and electronic boards. If science hadn’t proved that electric current travels through the surface of conductors, probably many cables would be completely manufactured with certain noble metals. Can you imagine if all cables were made of gold or silver? Surely, millions of dollars would be invested worldwide to allow transmission from power plants to homes.

Electroplating is one of the greatest discoveries in human history. Usually, during electroplating process, the piece to be plated is first cleaned with an acidic substance to remove any residue that could prevent adhesion of the noble metal. Then, a container is filled with a solution of small dissolved particles of noble metal. The piece is submerged in the solution and an electric current is applied, turning the piece into a kind of electromagnet that attracts noble metal particles to its surface. When the process is complete, the piece acquires a beautiful finish.
