Tin cry recrystallizing the metal. The low melting point of tin (only 232 °C, or about 500 K) makes re-casting easy. Tin anneals at reasonably-low temperature as well, normalizing tin's microstructure of crystallites/grains. Although the cry is most typical of tin, a similar effect occurs in other metals, such as niobium, indium, zinc, cadmium, gallium, and mercury. Tin cry A tin cry is the characteristic sound heard when a bar of tin is bent. Variously described as a "screaming" or "crackling" sound, the effect is caused by the crystal twinning in the metal. The sound is not particularly loud, despite terms like
