Two of them are gold (>80% Au), seven are made of copper alloys (70-80% Cu), one is lead (nearly 90% Pb), 28 items are made of tin alloys
, twenty are pewter, and eight are almost pure tin.

Boettinger of the National Institute of Standards and Technology (NIST) in Gaithersburg, Md., and his colleagues made thin bronze cantilevers, electroplated them with tin or tin alloys
, and then monitored flexing of the strips in response to compressive or tensile stresses in the films' microstructures.
According to customs figures, China exported 13,188 tonnes of unwrought and tin alloys
during the first two months of the year, a 90 per cent increase over last year's figure.
Nevertheless, tin in some form has been associated with the economic and cultural growth of civilization, food preservation and canning developed rapidly with the invention of tin-coated steel; transportation and high speed machinery became a reality with the invention of tin-base bearing metals; the casting of type metal was an important advance in printing technology bronze alloys became weapons, tools, and architectural objects; tin alloys
are used in organ pipes and bells, and telecommunications and electronic equipped depend upon the tin-lead soldered joint.
Another use for indium has been as an addition to bismuth, cadmium, lead, or tin alloys
to lower the melting point.
Annealed Tin 150-200[degrees]C for 2-8 hours Tin Alloys
Relatively small amounts (2-10%) of some alloying elements are recognized as a mitigation practice.
