Most of the companies do silver plating tin plating nickel plating etc. With the price of silver climbing tin becomes more economical even though ten times the amount of tin will be required to do the same job.

Bare copper presents satisfactory characteristics at temperatures up to approximately 100 c the most common pure metals used for plating copper and copper alloys for conductors are tin silver and nickel in special cases alloy coatings such as tin lead or composite coatings i e. Well the short answer is that tinned copper is copper coated by a base alloy such as solder better known as tin. Tin over nickel plated in multiple layers can be applied. Tinned copper wire is particularly useful in industrial cranes subways and marine projects where the tin coat makes the wire more resistant to water.

Compared to bare copper wires the tin coated copper wire variety is far more expensive. This also makes these copper wires last longer and they are found to be better suited to handling extremes of temperatures high humidity and wet. When copper is plated with alloys like tin then the already present properties of copper get further enhanced. Tinned copper wire can last up to 10 times longer than its non tinned counterpart and because solder is composed primarily of tin tinned wire is incredibly easy to solder.
