1.Definition and characteristics of tinplate

Tinplate is a special alloy material, different from ordinary iron materials, mainly containing iron, copper, zinc and other metal elements. Due to the addition of a large number of copper elements, the surface of the tinplate is deep yellow or deep red, and has good corrosion resistance, which is widely used in the production of metal products, such as business cards, locks, home decoration and so on.

2.the difference between tinplate and iron

Although the content of iron in tinplate is very high, it is not pure iron. In contrast, pure iron contains almost only iron, with no doping of other metallic elements. In addition, tinplate and iron are different in color, physical properties and chemical properties, so they are not the same substance.

3.The difference between tinplate and steel

Steel is a general term for iron-carbon alloys and also contains other elements, but tinplate does not belong to iron-carbon alloys. The main characteristics of steel are high strength and good toughness; The tinplate is characterized by its colorful appearance and is not as hard as ordinary iron materials.

To sum up, although the name of the tinplate with the word "iron", but in fact it is not pure iron, not steel, but an alloy material containing iron, copper, zinc and other elements. With its good corrosion resistance and appearance characteristics, tinplate is widely used in the production of metal products, such as business card boxes, locks, home decoration products.
