Properties
Silver-white metal, soft, with good ductility. Melting point 232 ℃, density of 7.29g / cm3. Non-toxic
Tin is a soft, silvery white metal but it with lead, zinc is very similar, but it looks to be more brighter. Its hardness is relatively low, you can cut it with a knife. It has good ductility, especially at a temperature of 100 ℃, can develop into a very thin foil, the thickness can be as thin as 0.04 mm or less.
Tin is also a low melting point metal, its melting point is only 232 ℃, so long as it can be with melted candle flame like quicksilver fluidity as well liquid.
Pure tin has a strange performance: When the tin bars and tin plate bending, will be issued a special cries like a popping sound. This sound is emitted by the friction between crystals caused. When the crystal deformation, will produce such friction. The strange thing is, if for tin alloy, in the deformation, but does not issue such a cry. Therefore, it is often based on the characteristics of tin to identify whether it was a piece of metal tin.
The main purpose of editing
Can be used as a coating material has a very wide range of uses in food, machinery, electronics, automotive, aerospace and other industrial sectors. In the float glass production, the molten glass floats on the surface of the molten tin pool is cooled and solidified.
