Tin Ingots

Description

Tin is a soft, malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent, a crackling sound known as the “tin cry” can be heard from the twinning of the crystals.Tin melts at low temperatures of about 232 deg C (450 deg F), the lowest in group 14.

The melting point is further lowered to 177.3 degc (351.1 deg F) for 11 nm particles. Commercial grades of tin 99.85% resist transformation because of the inhibiting effect of the small amounts of bismuth, antimony, lead, and silver present as impurities. Alloying elements such as copper, antimony, bismuth, cadmium, and silver increase its hardness.

Tin tends rather easily to form hard, brittle intermetallic phases, which are often undesirable. It does not form wide solid solution ranges in other metals in general, and few elements have appreciable solid solubility in tin. Simple eutectic systems, however, occur with bismuth, gallium, lead, thallium and zinc.

Tin is used in many ways in today’s everyday life and can be found back in electronics, food products, energy and transport applications. Tin has excellent properties for electrical conductivity and is an essential element in solder products. Refined tin is also consumed in chemicals, glass, copper alloys, plating and energy storage devices.
