Purpose of tin plating on copper busbar surface:

(1) Manufacturing tin cans: Because tin plating is non-toxic, it is widely used in areas that come into contact with food and beverages, specifically for making tin cans, as well as other items such as kitchen utensils, food knives and forks, ovens, etc.

(2) Electrical and Electronics Industry: Because tin is easy to solder and has good conductivity, it is widely used on electronic and electrical parts that require soldering.

(3) On copper wires: Improve the weldability of copper wires and the barrier between copper wire and insulation sheath.

(4) Activity: Because tin is soft, it can prevent scratches and serves as a solid lubricant.

(5) Prevent steel nitriding.
