because the ca is really made out of steel ( which is mostly iron). This makes the can strong and cheap. The tin protects the steel from corroded by the food in the can. If you put a thin layer of it you wont neat any more.
Because so-called tin cans are actually made of Steel (Iron/Carbon alloy) with a thin coating of tin to act as a corrosion inhibitor.
They are made from steel with a thin coating of tin to prevent corrosion.
Tin cans are typically made from steel coated with a thin layer of tin. The rusting of tin cans is primarily caused by the steel core of the can, which is more susceptible to rust when exposed to moisture and oxygen. Factors such as the thickness of the tin coating, the type of protective coatings, and the environment in which the cans are stored can also affect the rate of rusting.
Pre-1982 pennies are made of bronze, which is 95% copper plus 5% tin and/or zinc. Post-1982 pennies are zinc with a thin coating of copper.
Tin cans are actually made of steel that is coated with a thin layer of tin, which provides corrosion resistance. If the tin coating gets damaged or wears off, the underlying steel can rust when exposed to oxygen and moisture, leading to the appearance of rust on the can.
A typical bean tin is usually made of steel coated with tin. This coating helps prevent the steel from corroding and affecting the taste or quality of the beans inside the tin.
Broadly, 95% copper and 5% zinc. In 1943, they were produced from steel with a thin coating of zinc. In 1944 and 1945, there was a small (about 2%) amount of tin in place of a bit of the zinc.
If it is just a thin black coating this won't affect the tin can's thermal capacity, this is just the mass of the can times the specific heat of the material. What a black coating does do is affect the absorption and emission of radiated heat energy from the surface. So a black tin will heat up quicker in the sun but will also cool quicker in the shade.
A thin tin plate is a sheet of metal made of tin that has been flattened or rolled to create a thin and flat surface. These plates are often used in packaging materials or for decorative purposes due to their malleability and smooth texture.
By Galvanizing, Paint coating, Tin coating or Oiling
Tinplate is non ferrous, as it does not contain any iron.
As it's name suggests, a popcorn tin is made of tin. Tin is a metal but almost no cans, or popcorn tins, were actually made of tin. Rather they were made of tinplate, which is a thin layer of tin over a steel can. Today, aluminum cans have largely replaced tinplate cans - the can is aluminum while the top of the can is still made of tinplate.
