Solder tin POS10

POS10 solder. Solder — the metal or an alloy applied at the soldering to connection of preparations and having melting temperature below than the connected metals. Solders can be divided into two groups - soft and firm. Solders with a melting temperature up to 300 belong to solder With, and to firm - it is higher than 300 S. Odnako with the advent of a large number of solders on the basis of zinc and aluminum recently such classification has become already outdated. Solder generally is tin-lead. If solder contains 1 – 5% of antimony, then they are called antimonous, less than 1% - low-antimonous. Also bismuth, cadmium, indy can be a part of solders. Lead, antimony, bismuth and cadmium are toxic, cadmium is especially toxic! Melting temperatures of pure metals: lead (Pb) - 327 C, tin (Sn) - 232 C, antimony (Sb) - 631 C, bismuth (Bi) - 273 C, cadmium (CD) - 321 C, indiya (In) - 153. The Solders Tin-lead (STL) have melting temperature from 190 to 290 About the Most widespread of solder - POS-61 (61% of tin, the rest - lead), melting temperature 190 C, unit resistance 139 mkom.m; Tin alloys, tin-based alloys. Sb, Cu, Zn, Cd and other elements are O.'s part of page in different ratios of Pb (see the table). With many metals tin forms eutectics. Distinctive properties of tin alloys — the low melting temperature, small durability and hardness and satisfactory corrosion resistance; some tin alloys possess good antifriction properties. Tin alloys are applied mainly as fusible alloys, bearing materials, solders, semi-@. The tin and its alloys containing> 50% of Sn, have liquidus temperature in the range of 145 — 250 °C. The basis of such solders is made by four threefold and three double eutectics rich with tin. Quality and type of supply of POS10 solder corresponds: Non-ferrous metals, including rare, and their alloys of B51 of GOST 21930-76, GOST 21931-76, the GOST 28873-90 Use of POS10 Solder in the industry: for production of chushka, a round wire, the round bars filled with gumboil of tubes, powder, applied to a tinning and the soldering of contact surfaces of electric devices, devices, the relay for filling and a tinning of control traffic jams of fire chambers of engines.
