Aluminum and tinplate (tin-plated steel) are the two metals behind most rigid metal packaging.<\/strong> Aluminum is light and highly formable, so it is the usual choice for beverage cans, monobloc aerosols and tubes. Tinplate is thin steel coated with tin; it is stiffer and stronger, and it is the standard for food cans, paint and chemical cans, and many aerosol cans.<\/p>\n

Both metals are complete barriers to light, oxygen and moisture. Both are recycled at high rates. And both rely on an internal coating to keep the metal from reacting with the product inside.<\/p>\n

What is tinplate?<\/h2>\n

Tinplate is low-carbon steel sheet with a thin layer of tin applied to both sides, usually by electroplating. The tin protects the steel from rust and gives a surface that takes lacquer and print well. Tinplate also welds well, which is why it is the material for three-piece welded cans.<\/p>\n

A related material, tin-free steel (ECCS), uses a chromium coating instead of tin and is common for ends and closures. The name “tin can” is historical: a tinplate can is almost entirely steel.<\/p>\n

Which is lighter, and which is stronger?<\/h2>\n

Aluminum is about one-third the density of steel. That makes aluminum containers lighter to ship and easier to form into seamless shapes, such as two-piece beverage cans and monobloc aerosols.<\/p>\n

Steel is stiffer and stronger at a given thickness. That suits food cans that go through retort sterilization, sit under vacuum, and are stacked high in warehouses.<\/p>\n

Do aluminum and tinplate cans corrode?<\/h2>\n

Both can, which is why most food and beverage cans in either metal are coated inside.<\/p>\n
