Tinplate General Information
Tinplate is usually a cold-rolled low-carbon steel sheet with commercial pure tin on both sides, which combines the strength and formability of steel with the corrosion resistance, weldability and appearance of tin. Products are widely used in food packaging industry and other containers, stamping products, such as food cans, spray cans, bottle caps, gift cans, batteries, electronic accessories and so on.
