The Tinplate Guide

Steel Guru’s ‘The Tinplate Guide’ provides you the valuable information on tinplates and its uses.
Tinplate & The Environment
Tinplate is totally recyclable and all tinplate cans contain approximately 25% recycled metal. World wide, an estimated 355 million tons of steel is recycled every year. Both types of steelmaking, Basic Oxygen Steelmaking and Electric Arc steelmaking use steel scrap as an essential ingredient, in fact Electric Arc Furnace production uses steel scrap for virtually 100% of its charge. The use of scrap steel saves up to 70% of the energy & 40% of water required in production of steel from virgin materials and it saves precious natural resources. For every ton of steel cans recycled, 1.5 tons of iron ore, 0.5 tons of coal is saved
Metallurgical Aspect
Tinplate has four layers of different materials on steel base, starting from Tin iron alloy, Free Tin, Tin Oxide film and oil film and adaptability for a specific purpose depends upon the properties of a given layer and steel base. For a part of a toy, where deep drawing is done, the controlling factor is the quality of steel base. Oil film plays an important role in feeding in automatic equipment for fabrication of auto parts and the layer of tin oxide influences the adhesion of lacquer and enamels. However, the optimum properties of each layer are standardized due to mass production facilities
Product Description
Tinplate is low carbon mild steel, coated on both top and bottom surfaces with an electrolytic deposition of tin. The deposited tin exists as alloyed and free tin and has a passivated surface as well as a coating of oil. It is known as Electrolytic Tinplate (ETP) but is more accurately called the Electrolytic Tin Coated Steel (ETCS)

Use of Tinplate
Tin mill products are used for a wide variety of applications. Some are quite obvious such as food and beverage cans. Others are less obvious. The following is a list of some of the most common applications of tin mill products:
Tin mill products, principally developed as food packaging material, now serve many functional purposes. The traditional uses of tin mill products can be broadly classified as follows:
• Cans and Closures
• Construction Products
• Oil Filters and other automotive applications
• Miscellaneous Applications
