Tin is a silvery-white, highly lustrous metal that is soft and ductile. The density is 7280 kg/m3. Tensile strength 35 N mm-2, Brinell hardness 12 HB, melting point 232ºC, boiling point 2430ºC , relative atomic mass 118.710 , atomic number 50 and specific thermal conductivity 66 W/mK. Below 13.2ºC it occurs with the modification, cubic -, which has the diamond lattice. Tin in this case is gray and brittle, the objects slowly decompose to gray powder, avoidable by admixing bismuth. The β-modification is tetragonal and very soft and pliable. The transformation from β to α is very slow, so Sn can be used below 13.2ºC. (At low temperatures, for example -40ºC, the transformation takes place in a few hours). At temperatures above 116ºC the metal becomes brittle (grain tin).

Use and processing of tin:

Tin provides excellent corrosion protection as a coating metal. Tin coatings are produced by hot-dip tinning, scatter tinning, electroplating and precipitation. The first two processes start from the metal, the others from salt solutions. The coating metal is used for machine parts in the food industry (meat processing machines, fruit presses, as jacket pipes [tin-lined lead pipes to protect against lead-attacking water]) or tin pipes for mineral water or beer lines. It is mainly used for the production of tinplate for food containers. Furthermore, tin is used as an alloying metal for tin bronze (80 to 90% Cu + 20 to 10% Sn), soft solders (solder, 2 to 90% Sn + 98 to 10% Pb), Britannia metal (70 to 80% Sn + Cu + Sb), gunmetal, lettering and bearing metals.


The metal tin has probably been known since 3500 BC; in the Taurus Mountains of southern Turkey, for example, the Kestel tin mine and the Göltepe tin processing plant were discovered - dated to about 3000 BC. Items made of tin were also found in an Egyptian tomb from the 18th Dynasty (~1500 BC). Due to the alloy bronze, whose components are copper and tin, it is of great importance (Bronze Age). The Roman writer Pliny called tin plumbum album (white lead; lead, on the other hand, was plumbum nigrum = black lead). The high demand for tin is even cited as a reason for the Roman occupation of Britain - the southwestern region of Cornwall was then home to significant ore deposits. In Latin, tin is called stannum, which is where the chemical symbol Sn comes from. The chemical symbol Sn is derived from this. Long after bronze was displaced by iron, tin regained great importance in the mid-19th century through the industrial production of tinplate.

Production and occurrence

Tin can be easily extracted from tinstone (cassiterite, a reddish brown/black ore also known as tin oxide, SnO2). For this purpose, the ore is first crushed and then enriched by various processes (slurry, electrical/magnetic separation). After reduction with carbon, the tin is heated just above its melting temperature so that it can flow off without higher melting impurities. Today, much of it is recovered by recycling, and here by electrolysis. In the earth's crust, it is present in a proportion of about 0.0035 percent by mass.
