Tinplate

Tinplate, thin sheet steel or iron coated with commercially pure tin by a hot-dip or electrolytic process. Tinplate is used primarily for the manufacture of cans. The tin protects the steel against rusting and corrosion and also acts as a lubricant when the steel passes between dies during the shaping of the cans. Recently developed tinplate is almost one-third more corrosion-resistant than the earlier type of plate. Other uses of tinplate are in the coating of copper wire and electrical connections.
