Typically they are coated or plated in corrosion resistant substances.
Zinc and tin are the two metals usually used for the prevention of corrosion. However, tin is the only one that you can really cut into tiny pieces.
Tin (Sn) is used to coat iron cans because it prevents corrosion as it is less reactive than Iron and hence lower in the Reactivity Series than Iron.
Aluminium is now cheap, easily machined, has a low density and is resistant to corrosion.
A food can is made of steel with a thin tin layer on the inside. This is because of the galvanic series (based on a salt water solution). Basically there is a table that contains the corrosion order for a number of metals and alloys, the lower end of the list are anode materials (positive) and the materials higher up the table are cathode materials (negative). The positive materials are faster at corroding when submerged in a salt water solution which is were steel is located. This means that the steel will corrode relatively quickly which would then effect the contents of the can. Therefore a tin coating is used as tin is much higher in the series so this means that it will not corrode as quickly as the steel. Hope this helps
Food cans are made of Heavy Aluminumanswer 2 Most food cans today are still made of mild steel, coated inside to resist corrosion. Aluminium has made great inroads into the beverage industry, and to the fish products to some extent.Aluminium is light, easily formed, and in appropriate circumstances, is highly recyclable. It is more energy-demanding to produce than steel, and thus is more expensive.Both metals should be recycled today.
they reduce its contact to moisture and make th emetal thin instead of fat because it will make it overwieght
Tin and enamels (lacquers) are used to coat cans. See Related Links.
It is very good for making cans, but the inside should usually be coated (especially if the contents will be acidic) with a plastic film to prevent corrosion of the steel.
When food is packaged in cans, air is sucked out of the can to help prevent the food inside from spoiling. Some manufacturers add preservatives to food to help keep it fresh longer.

Different manufacturers have always had different soup cans.
The metal used to make garbage cans is galvanized steel. This steel is meant to withstand the toughest enviroments to last you a lifetime. These galvanized steel garbage cans are treated with zinc to help corrosion resistance.
Tin (Sn) is used to coat iron cans because it prevents corrosion as it is less reactive than Iron and hence lower in the Reactivity Series than Iron.
The government is responsible for putting more trash cans because they have the money to put more trash cans. They can use the money to buy the trash cans and put the trash cans in the community to prevent littering.
1. Steel cans arrive at a recycling center. 2. The cans are removed from the conveyor belt with an electromagnet. 3. The cans are smashed and baled. 4. The steel cans are delivered to a facility where they are melted and cast into ingots. 5. The steel ingots are rolled out into sheets. 6. These sheets are delivered to manufacturers that turn them into new cans.
Iron can are electroplated with tin to prevent the cans from rusting. Tin is a metal that resists rust.
They are made from steel with a thin coating of tin to prevent corrosion.
