Definitions

  • the present invention relates to a zinc aluminum alloy, a wire producible therefrom, and uses of the zinc aluminum alloy of the present invention.
  • soldering of the aluminum components is done with the help of solder pastes (metal powder and flux) or by supplying a solid wire which is coated with flux or by means of a filler wire.
  • solder pastes metal powder and flux
  • a solid wire which is coated with flux or by means of a filler wire.
  • the known brazing materials have a low creep resistance. Since the placement of the rings on the pipes and the soldering process takes place on different systems or partially in separate production facilities or separated in time, the attached rings lose their clamping voltage, move or even fall off the pipes.
  • EP 1 462 207 A1 discloses a zinc alloy containing 1 to 25 wt .-% aluminum in addition to the usual impurities.
  • This alloy may contain up to 500 ppm Mg, up to 500 ppm Cr, up to 2000 ppm Mn, up to 300 ppm Li, up to 4% Cu, up to 50 ppm B, up to 500 ppm Ti and / or up to 1000 ppm Si, in addition to the usual impurities. Rest zinc.
  • the zinc alloy is suitable for use in wire form for inert gas welding or inert gas soldering.
  • JP 1162740 discloses a zinc aluminum alloy with 10-25% aluminum, 0.05-0.3% copper, 0.005-3.0% each magnesium, silicon and manganese, balance zinc. This alloy is suitable for use in various devices and systems.
  • the object of the present invention is to provide an alloy with improved creep resistance in order to provide greater production reliability in the preparation of parts to be soldered.
  • the alloy to be created should also have significantly fewer pores (shrinkage porosity) than those of the prior art.
  • a Zinc aluminum alloy which has an Al content of 12% - 22%; a Cu content of 0.5% - 1.0%; an Mg content of 0.001% -0.1%, an Mn content of 0.1% -0.5%; has an Si content of 0.1% -0.8% balanced with Zn to 100%.
  • the newly developed alloy offers more than 20% better creep resistance compared to standard alloys and allows a secure hold of the rings on the pipe.
  • the new alloy shows over that of the prior art ( FIG. 1 ) surprisingly also a very dense structure (see FIG. 2 ).
  • a zinc aluminum alloy with an Al content of 18% has proven particularly useful; a Cu content of 0.8%; an Mg content of 0.03%; a Mn content of 0.18%; an Si content of 0.4% and a Zn content of 80.59%.
  • the zinc aluminum alloy according to the invention can be converted into a wire in a manner known per se. This is usually done by a multi-stage rolling and drawing process.
  • the wire according to the invention has an improved creep behavior and less relaxation under tension.
  • DIN EN 10319-1 in the relaxation test under tensile stress at room temperature at a test voltage of 100 MPa, after a test time of 16 h, residual stresses of 40% -60% of the test voltage are determined.
  • the wire according to the invention has only a small number of pores and good wettability.
  • Example 1 Production of a Wire from the Inventive Alloy
  • the alloy is produced by adding the individual alloying elements Al, Cu, Si, Mn, and Mg to a standard alloy with simultaneous stirring.
  • master alloys such as for example CuSi for the production of the multicomponent alloy according to the invention is possible.
  • Mg is added as the last alloying element.
  • the wire is made from the cast strand in a multi-stage rolling and drawing process.
  • the improved creep properties of the zinc alloy according to the invention are determined in the relaxation test.
  • the samples are subjected to a force of 100 MPa (+/- 2 MPa) at room temperature in the testing machine and the voltage drop in the sample is recorded at a constant elongation over a period of up to 16 hours.
