Tin is a silvery white but soft metal that is similar to lead and zinc but looks lighter. Its hardness is relatively low, with a knife you can cut it. It has good ductility, especially in the temperature of 100 ℃, can be made into a very thin tin foil, the thickness can be as thin as 0.04 mm. Tin is also a low-melting-point metal with a melting point of only 232 ° C. Therefore, it can be melted into a very fluid liquid like mercury by simply using a candle flame. Pure tin has a peculiar property: when the tin bars and tin plates bend, they emit a special, crackling sound like a weeping sound. This sound is caused by the friction between the crystals. When the crystal deformation, it will produce such friction. Strangely enough, if you switch to a tin alloy, you will not be able to make such a cry when it is deformed. Therefore, people often according to the characteristics of tin to identify a piece of metal is not tin. One of the main uses of metallic tin is to make tinplate. Tinplate People often say "tinplate", which is tin-plated tinplate. Do not look thin layer of tin above, but it is very useful "coat." Metal jacket put on this coat, not only beautiful, but also get a lot of good nature. So, tin made "coat" What are the good nature of it? In short, that is: both anti-corrosion, but also anti-virus. Why tin tin has such a good nature? This is inseparable from the nature of tin. It turned out that the chemical properties of tin is very stable. It will not react with water, even if it is in contact with moist air for a long time, it will gradually form a dense oxide film on its surface. This film can prevent the tin from being oxidized Tin metal corrosion-resistant reasons. In addition, the role of tin and inorganic acid is very slow, almost no effect with organic acids, and tin salts are generally non-toxic, therefore, tinplate is often used as food packaging materials, such as  tin food packaging  , Biscuit boxes and so on.
