Tin Alloys

Tin Alloys

 

alloys of tin with varying proportions of other elements, including Pb, Sb, Cu, Zn, and Cd (see Table 1).

Tin combines with a number of metals to form eutectics. These alloys exhibit low melting points, low strength and hardness, and good anticorrosive properties; certain tin alloys also have low coefficients of friction. Tin alloys are primarily used for tinning and as fusible alloys, bearing metals, and solders.

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.
