Copper wire possesses exceptional conductivity, making it an essential component in many electrical systems. Coating the wire with tin provides it with even more durability and strength.


In tinned copper wire, each strand of copper is coated with tin.


There are two ways to produce tinned copper wire. The first is known as hot dipping, in which the strands of copper are dipped into melted tin. The other option is electroplating, which uses a rectifier and electrical charge to tin the copper.


Tinned copper wire lasts up to 10 times longer than non-tinned wire. It also resists water corrosion and provides enhanced conductivity.


Due to its improved water resistance, tinned copper wire is often used in boating and various marine projects. It can also be found in overhead power sources such as those in the light and heavy transit systems.


Tinned copper wire is more expensive than non-tinned wire. However, the initial expenditure can prove prudent over time thanks to the tinned copper wire's increased longevity.
