Bronze tin is soldered with silver, copper-zinc and tin-lead solders. High-tin bronze is undesirable to solder copper-zinc solders due to the proximity of the melting point of solders and the melting point of the base metal. Soldering of tin bronzes is carried out by any known methods: gas flame burners, soldering iron, heating of HDTV, contact heating, in furnaces in which the atmosphere is controlled, in salt baths. Heating of the parts, in this case, it is necessary to carry out gradually, since the base metal at a high heating rate is prone to reddishness.
They are soldered with solders with fluxes, used in the soldering of tin bronzes. Places of soldering should be fluxed very carefully, because the resulting lead oxides on the surface can prevent flow into the gap of the solder.
They are soldered with the use of orthophosphoric acid. High-temperature brazing of manganese bronzes is carried out with the use of fluxes, which include fluorides and fluoroborates of alkali metals.
Their soldering is much more complicated than other copper alloys; It is necessary to use silver solders with a flux immediately after mechanical stripping.
Are soldered by any solder and method, and also by pure copper. Soldering with copper in an oven where the atmosphere is controlled must be carried out at high heating rates, since the base metal dissolves in solder during prolonged soldering, significantly reducing the strength of the seam.
They have high mechanical properties among alloys of copper, so they are widely used in engineering. To avoid oxidation and the formation of brittle intermetallides, such bronze should be soldered in the seam using fast heating methods. By introducing nickel into the solders, the strength and ductility of the aluminum bronze compounds are enhanced.
Other types of bronze
Simple bronze (double copper alloys with aluminum), more complex bronze in composition with the addition of iron, manganese, nickel and other elements are used in a wide variety of industries. On the surface of siliceous and aluminum bronzes, an oxide film is formed, which with the use of ordinary fluxes is difficult to remove. Before soldering, it is necessary to treat the product in hydrofluoric or hydrofluoric acid.
