Tin.

tin (Latin Stannum; denoted by the symbol Sn) component The fourth group, the fifth period of the periodic system D. I. Mendeleev, with atomic number 50. Refers to the group light metals. Under normal conditions, the simple substance tin is plastic. a ductile and light-melting shiny metal of silvery white color.

Tin Used mainly as safe, non-toxic, corrosion-resistant coating in pure form or in alloys with other metals. Major industrial use of tin - in white tin (tinted iron) for the manufacture of food containers products, in solders for electronics, in house pipelines, in bearings Alloys and coatings of tin and its alloys. The most important alloy of tin is bronze (c). copper. Another known alloy - peuter - is used to make dishes. There has been a resurgence of interest in the use of metal since it The most environmentally friendly among heavy non-ferrous metals. Used to create superconducting wires based on the Nb3Sn intermetallic connection.

Tin powderis produced by the method of spraying. There are the following brands of tin powder: POE, P01, P02, PHO. P04. Tin powder is made from tin grades 01 and 02 according to GOST 860, but other grades of tin are permissible. Tin powder should be without mechanical inclusions and lumps. The bulk density of tin powder grades P02 and PHO within the range of 3.2-4.0 g/cm3. The bulk density of tin powder grades POE and PO1 in the range of 3.4-4.0 g / cm3. The bulk density of tin powder P04 in the range of 3.6-3.9 g / cm3. Tin powder grades P01 and POE has a uniform granulometric composition. The powder is non-toxic.

Tin powder is used for coatings, in the engineering industry; for the production of electric coal products, including electric brushes, lighting and elemental coals, bronze-graphite bearings, bushings, sealing materials, electrical contacts, permanent magnets and structural products. and other metal ceramic compositions in various industries.
