Tin is a silvery, malleable metal that oxidises easily at ambient temperature, changes colour to a duller grey, and is resistant to corrosion. It is found in many alloys and is used to coat other metals to protect them from corrosion. One of the most striking features of tin is that it suffers from tin pest in certain conditions. When bending a bar made of this metal, a characteristic sound called the cry of tin is produced, generated by the friction of the crystals it is composed of. It begins to decompose and turn into a grey powder at temperatures of below -18 ºC; this process is known as tin plague. Pure tin has two allotropic variants: grey tin, a non-metallic, semiconductive powder with a cubic structure and which is stable at temperatures of below 13.2 °C, which is very brittle and has a lower specific gravity than white tin. White tin is a normal, metallic, electrically conductive element with a tetragonal structure and stable at temperatures of above 13.2 °C.
