Tin plated copper vs copper. Compared to bare copper wires the tin coated copper wire variety is far more expensive. Which plating is best for copper copper and copper aluminium and aluminium aluminium contacts. 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. What is tinned copper.

Every tin plated copper alloy experiences the formation of copper tin intermetallic compounds cu 6 sn 5 and cu 3 sn at the interface of the tin and the base metal. 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. Sounds simple but there s more to it than that. Tinned copper vs bare copper the advantages of tinned copper are impossible to deny.

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. These include high thermal and electrical conductivity ease of manufacture high recyclability and good corrosion resistance. An intermetallic compound consists of two or more elements always with the same precise ratio of atoms in this case 6 5 and 3 1. Tinned copper wire is particularly useful in industrial cranes subways and marine projects where the tin coat makes the wire more resistant to water.

Cost of tin vs silver plating may differ depending upon location but in the usa silver plating is cheaper than tin plating for whatever reason. 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. When copper is plated with alloys like tin then the already present properties of copper get further enhanced. Well the short answer is that tinned copper is copper coated by a base alloy such as solder better known as tin.

Throughout the industry there are different thoughts about which metal is better for plating copper tin or silver. Download pdf 317 kb general. Grounding with copper tinning vs. Sanj wish mumbai india.

10 microns of tin will out perform 1 micron of silver. Follow along as we show just how important it is. Tin over nickel plated in multiple layers can be applied.
