Tin Ingot is a silvery-white metal, soft and ductile. Melting point 232°C, density 7.29 g/cm3, non-toxic. Very similar to lead and zinc, but looks brighter. It has a relatively low hardness and can be cut with a knife. It has good ductility, especially at 100°C, it can be stretched into a very thin tin foil with a thickness of less than 0.04mm.
Tin is also a low-melting metal, with a melting point of only 232°C, so it can be melted into a liquid with good fluidity, like mercury, with the help of a candle flame.
Pure tin has a special property: when bending tin rods and tin plates, a special breaking sound is heard, similar to crying. This sound is caused by friction between crystals. When a crystal is deformed, such friction occurs. Oddly enough, if a tin alloy is used instead, this "weeping sound" will not be made when warped. Therefore, people often use this characteristic of tin to determine whether a piece of metal is tin.
