In order to do tin coating on copper wire the material needs to go through a serious of process. First, the Electrolytic Copper Wire is drawn into the specific size required through various machinery. Secondly, the material is annealed and then tin coated is done on it by two process:- Electrolytic Process This is a process in which the material passes through chemical tank and with the help of electric current on the tin slab the tin coating on the copper wire is done which comes evenly onto the material as required. Hot Dip Process In this process the tin slab is melted into an electric pot and the material is being made passed through it which results in tin coating on it.
