Definitions

  • the invention relates to the use of a high brass alloy Cold formability for sanitary pipes.
  • Sanitary pipes are in the present Context those, which are preferably in the first stage of the household Waste water management, namely in the siphon area, are used. It is about around thin-walled pipes with a wall thickness of around 0.4 - 1 mm, Use as partially curved components, high flexibility, d. H. Cold formability, must have.
  • the pipes must be a good one Have surface and be chrome-plated.
  • JP 59 025 938 A is already a copper alloy with 60 to 63% Cu, 2 to 3.7% Pb, 0.02 to 0.06% P, balance zinc known. This alloy is suitable for hot water pipes. she has as a structure beta phase, in which the beta particles are surrounded by alpha particles to achieve dezincification resistance.
  • the object of the invention in contrast, is to show an alloy which Cold formability of approximately MS 63 brass has, by using cheaper It is inexpensive to manufacture scrap.
  • the alloy according to the invention has a copper equivalent of that must have from MS 63, due to impurities contained in the alloy such as especially iron as well as the use of lead however a lower actual Has copper content and still has good cold formability. In fact achieved one with the alloy according to the invention elongations at break of 50%, whereas comparable values for MS 63 are around 60%.
  • a further development of the invention provides that the alloy additionally 0.02 to 0.2% As or P, which further improves the dezincification resistance.
  • the minimum value of the copper content is 60.5% and the maximum value for the copper 63.2%.
  • the minimum value for copper results from a high one Lead and iron content, the maximum value for the copper content results from the Minimum value for lead without further contamination.

  1. Utilisation d'un alliage de laiton à haute formabilité à froid, pour des tubes de sanitaires, constitué de 60,5 à 63,2 % de Cu, 2 % à 3,7 % de Pb, au choix encore de 0,02 à 0,2 % d'As ou de P, le reste étant Zn, et contenant en outre comme impuretés usuelles jusqu'à 0,35 % Fe, qui est recuit à une température d'environ 640°C pendant 10 à 40 min, l'équivalent de cuivre efficace étant de 63 % à 64,5 % Cu et la valeur minimale et la valeur maximale du cuivre étant calculées, pour un équivalent Cu' de cuivre souhaité, prédéterminé, selon la formule ci-après : Cumin = 100 - Pb(%) - Fe(%)100 x Cu'min Cumax = 100 - Pb(%)100 x Cu'max
