The reason of plating the copper is to prevent oxidation in the air.
If used as is, the appearance will turn black, so tin plating is applied.
[The characteristics and weaknesses of copper]
Copper has excellent electrical and thermal conductivity, hence it is often used in power-related parts.
However, if copper is used without plating, it will oxidize in the air, becoming black and producing copper oxide as a byproduct, which has the disadvantage of increasing surface resistance.
To avoid this, copper is plated to compensate for the weakness.
Another interesting fact: copper was once considered to be dangerous when oxidized, hence tin coating was used to prevent direct contact between copper and food.
The toxicity of copper oxidation has now been rejected, thus there is no concern; yet, tin plating is still employed to prevent the flavor of copper from transferring to food.
