Copper Flat with Tin Coating

The tinned copper strip has good stability, strong corrosion resistance and anti-discoloration ability, and has good weldability and ductility. In the case of sealing, the thin tin layer can have good protection and is not poisonous with the product formed by organic matter.

Tinned copper is primarily used for protection against oxidation and corrosion. In climates where copper has long-term exposure to water, the oxygen will combine with the metal and form copper oxide, weakening the bonds of the metal.

The tin plating helps to protect the underlying copper from corrosion, improving the reliability and lifespan of the busbars.
