Definitions

  • the present invention relates to the use of a low-migration copper alloy for the production of components for gas and sanitary installation, especially for components that are used in drinking water installation and directly with the in the components, usually pipes, fittings and fittings, guided drinking water in Contact, as well as components consisting of such copper alloy.
  • the GB-1 443 090 discloses a dezincification-enhanced copper alloy having between 80 and 90 weight percent copper, between 6.3 and 17.5 weight percent zinc, and between 2.8 and 4.75 weight percent silicon as essential alloying ingredients between 0.03 and 0.05% by weight of arsenic.
  • 443,090 proposed a heat treatment of the cast parts. In this heat treatment, the cast parts are annealed at temperatures between 600 ° C and 750 ° C for a period of 5 to 10 days and then quenched. This heat treatment is carried out with the aim of obtaining the ⁇ and ⁇ phases to be preferred in view of the corrosion. By quenching in particular the formation of phases is to be avoided, the corrosion resistance is low, so the p and ⁇ phase.
  • a copper alloy containing up to 10% by weight of aluminum is known and up to 5 wt .-% iron and which is used for the production of water-bearing components of water installations.
  • this alloy shows inadequate corrosion behavior and, in particular, excessive migration of metal ions into the water.
  • the present invention is based on the problem of providing a migration behavior improved copper alloy, which is particularly suitable for the production of media-carrying gas or water pipes and their parts and the good corrosion resistance to the media, good strength and good machinability and castability Has.
  • machinability in particular, the chipping properties of the copper alloy are important.
  • the invention wants to specify corresponding media-carrying components, in particular fittings or fittings, as well as an advantageous use of the copper alloy according to the invention.
  • a copper alloy having the features of claim 1 comprises between 2 and 4.5% by weight of silicon, between 1 and 15% by weight of zinc and between 0.05 and 2% by weight of manganese.
  • the copper alloy may contain between 0.05 and 0.4% by weight of aluminum and / or between 0.05 and 2% by weight of tin.
  • the remainder of the alloy contains copper and unavoidable impurities. These impurities are preferably limited to a content of 0.5% by weight. Most preferably, the upper limit for the impurities is 0.25%. This upper limit applies in particular to the cumulative nickel and lead content in the alloy, which has proven to be a particularly effective measure for suppressing the migration of lead or nickel.
  • the alloy is preferably free of lead and / or nickel.
  • a lead-free alloy an alloy is considered in which the content of lead is less than 0.25%.
  • the nickel-free alloy is considered to be an alloy in which the nickel content is less than 0.15%.
  • the components in question for media-carrying lines easily with the usual casting process, for example, in the sand, mold, spin or continuous casting can be produced.
  • the cooling conditions from the melt there are no special requirements.
  • the casting thus obtained can be processed well spanariad.
  • the casting is preferably annealed at between 400 ° C and 800 ° C for at least half an hour.
  • the heat treatment is carried out in a temperature interval of between 600 ° C and 700 ° C.
  • the glow time can be any length. In terms of economic constraints, however, this is set at between 2 and 16 hours. In this glow time, the Aufzeitphase is not included.
  • the annealing takes place in particular with the aim of adjusting the ⁇ -phase in the cast component, which, according to the present inventions, enables the combination of different properties to be achieved. It should be noted, however, that even the vast majority of the necessary alloying elements copper, zinc and silicon solidifies in a natural cooling from the melt without separate heat treatment in the form of ⁇ -mixed crystals.
  • the upper limit of the silicon content is set to 4.5 wt% not least in view of the machinability of the alloy.
  • the zinc content limited to 15 wt .-%.
  • a minimum content of 1% by weight of zinc guarantees a minimum of machinability.
  • Manganese is added to the alloy within the limits of 0.05 to 2% by weight in order to improve the microstructure. Manganese refines the microstructure and positively influences the solidification behavior of the copper alloy. However, the manganese content is limited to 2% by weight in consideration of the migration tendency of manganese.
  • Limiting the sum of the impurities to a maximum of 0.5% by weight limits the content of ingredients that may possibly migrate into the drinking water to a minimum that is also economically desirable. With a further limited upper limit of the unavoidable impurities of 0.25% by weight, a higher security against migration, but at the expense of manufacturing costs, can be achieved.
  • the alloy contains between 5 and 15% by weight of zinc. In this limited interval, the best possible combination of corrosion resistance and machinability can be achieved.
  • the silicon content is set at between 2.8% by weight and 4% by weight.
  • the content is preferably set at 0.2 to 0.6 wt .-%.
  • the alloy preferably contains no nickel or lead at all for the same reasons.
  • the copper content in the alloy should be at least 80 and not more than 96.95% by weight.
  • the use of the copper alloy for the production of components for media-carrying gas or water pipes is proposed. These are in particular those components to understand that form drinking water pipes, in particular fittings and fittings and parts thereof. Not least because of the good stress-strain properties
  • the copper alloy should preferably be made of a compression connector of the copper alloy according to the invention.
  • the compression connectors can either be designed as separate components or be provided with material or positive fit to the fitting or the fitting.
  • the press connectors can be realized as integral components in the casting of the fitting or fitting from the copper alloy.
  • the casting alloy is particularly suitable for producing an element of a press connection arrangement, as for example from the EP 0 343 395 or the DE 10 2004 031 247 is known.
  • Figs. 1 to 4 show the time course of the release of certain metal ions in a measurement arrangement according to DIN 50931-1 over a total period of 26 weeks. DIN specifies the test arrangement and test conditions with which the corrosion probability of materials for metallic components of a drinking water installation can be determined in the case of corrosive contamination of drinking water.
  • the measurement results with the exemplary embodiment of the copper alloy are marked with A.
  • the comparison measurement with the gunmetal alloy with B.
  • FIGS. 1 to 3 also contain a limit value according to the German Drinking Water Ordinance (TrinkwV) for the delivery of certain ions to water and the parameter value W (15) to be observed during migration tests.
  • This parameter value W (15) must be adhered to if it is intended to avoid exceeding the value of the TrinkwV when using the tested component.
  • the parameter value W (15) results from the product of the limit value according to the TrinkwV and the ratio of the form factors A and B.
  • the form factor A results from the ratio of the water-contacted surface of the material to the water-contacting surface of the entire test section.
  • the form factor B is a normalization factor in accordance with DIN 50930-6, which takes into account the type of components.
  • FIG. 1 illustrates that the lead-release quantity of the gunmetal alloy drops from a very high value, greater than 50 ⁇ g / l, almost exponentially within the first four weeks of testing to a value which is just above the limit of the German drinking water regulations of 10 ⁇ g / l. l after 12 to 26 weeks of testing.
  • this significant excess is attributed to the fact that lead, which had been introduced to the surface of the component to be tested, migrated into the drinking water as a result of the processing and production of the test part.
  • the near-surface lead has migrated out of the sample and the amount of discharged lead remains approximately constant.
  • the exemplary embodiment according to A gives virtually no lead to the drinking water. Even an increased value at the beginning of the experiments can not be seen. Since the measured values are at the limit of the resolution of the measurement analysis, the fluctuations in the measured values are attributed to the measuring accuracy of the measuring apparatus. Essentially, the measured value for the lead release in the sample remains well below the limit value of the PrincipalwV of 10 ⁇ g / l.
  • the comparison sample from the gunmetal alloy shows a typical course in which the conventional alloy after nine weeks exceeds the limit value according to the German UlwV, after a maximum in about the 18th Week slowly back to the limit value of the TrinkwV.
  • the copper alloy A gives no appreciable nickel ions to the drinking water.
  • the measured values of about 2 ⁇ g / l are in the range of the resolution of the analysis related to the measuring instruments.
  • Fig. 4 shows the amount of zinc released by the alloy into the drinking water.
  • no limit is set according to the TrinkwV.
  • the course of the zinc release in the case of the copper alloy A differs considerably from the corresponding course for the comparative alloy B.
  • the migration of the embodiment A of the alloy of zinc is below 100 ⁇ g / l at all times.
  • the conventional alloy B exceeds this value many times.
  • FIGS. 1 to 4 illustrate the advantages of the copper alloy A, in particular the influence of the silicon for suppressing unwanted metal ion migration into the drinking water.
