Definitions
- the invention relates to an electrical connection element containing a copper-zinc alloy according to the preamble of claim 1.
- a first step in this direction was the development of precipitation-hardening copper alloys, for example based on the system
- CuCrAgFeTiSi with 46 MS / m and strengths up to 610 MPa Another important advantage of this alloy is the very good relaxation resistance of the material when used at elevated temperatures up to 200 ° C. This type of alloy can cover applications in the automotive, industrial electronics and telecommunications sectors. In addition, bronze materials are used, which are characterized by a fine
- Forming zones is much lower than when using standard bronzes. Thus, subsequent coatings can be carried out with a smaller layer thickness, which can achieve considerable cost savings in further processing.
- the electrical conductivity is identical to that of standard bronzes and is around 7.5 to 12 MS / m.
- the material is high strength, has with

- the alloy spectrum is rounded off by further precipitation-hardening materials.
- these include, for example, CuNi1 Pb1 P and CuNiPbO, 5P as low-alloy copper material with high strength, good conductivity of at least 32 MS / m and good machinability. Due to the Pb content, the material is particularly suitable for machining machined plug-in contacts in electrical engineering and electronics.
- the invention has the object of developing an electrical connection element made of a lead-free or lead-free copper alloy.
- the invention is represented by the features of claim 1.
- the other dependent claims give advantageous embodiments and further developments of the invention.
- the invention includes the technical teaching for the construction of an electrical connection element containing a copper-zinc alloy.
- the copper-zinc alloy consists of (in% by weight):
- iron-nickel-manganese-containing mixed silicides are incorporated in the matrix.
- the microstructure consists of an ⁇ -matrix, in the inclusions of ß-phase from 5 to 45 vol .-% and iron-nickel-manganese-containing
- Mixed silicides are contained up to 20 vol .-%. Furthermore, the structure contains the iron-nickel-manganese-containing mixed silicides with a stalk-like shape and iron-nickel-enriched mixed silicides with a globular shape.
- the alloy composition according to the invention is suitable for electrical connection elements. So far, an application of such alloys according to the German patent application DE 10 2007 029 991 A1 of the Applicant was only for a use for
- the invention is based on the idea to provide an electrical connection element with a copper-zinc alloy with embedded iron-nickel-manganese-containing mixed silicides, which can be prepared in particular by means of the continuous or semi-continuous continuous casting process. Due to the mixed silicide formation and structure formation, the copper-zinc alloy has a very high electrical conductivity for this material group.
- the alloy has high hardness and strength values, yet a necessary degree of ductility, expressed by the elongation at break value in a tensile test, is ensured.
- the subject invention proves to be particularly suitable for electrical
- Connecting elements such as turned connectors
- Plug-in devices electrical terminals, optionally with screw connections.
- the alloy has a high during cold forming
- the material is also particularly suitable for machining electrical connecting elements.
- the good machinability is already achieved by a ß-phase of 5 vol .-%. At higher levels, up to 45% by volume of ⁇ -phase also improves chip formation during the cutting process, in that desirably short chips are formed. With a content of ⁇ -phase below 5% by volume, the machinability in the use as automatic material for high metal removal rates is no longer satisfactory. With a ⁇ -phase content of more than 45% by volume, it can be seen that the toughness of the material and the temperature resistance of the microstructure deteriorate. The final state of the alloy from the respective manufacturing process leads to a ⁇ -phase, which is embedded like an island in a microstructure of an ⁇ -matrix. Such ß-phase islands are particularly favorable for the machinability and the
- Corrosion resistance of the alloy A particularly high surface quality of the machined surfaces is achieved with a ⁇ -phase content, however, in particular from 10 to 25% by volume. In the specified volume interval of 5 to 45 vol .-% of ß-phase also a comparatively low tool wear, so that the
- the particular advantage of the alloy according to the invention is based on an optimized combination of properties for the purposes in the form of a

- this material is predestined for special applications where a high degree of plasticizability is required despite the high hardness and strength requirements.
- the copper-zinc alloy in an advantageous embodiment of the invention, the copper-zinc alloy
- Toughness properties and electrical conductivity optionally further improved with a final stress relief annealing.
- the final flash annealing is carried out at 300 ° C to 400 ° C for 3 to 4 hours.
- the copper-zinc alloy may contain 33.5 to 36.0% Zn. At these higher levels of zinc, it is still possible to use those required for electrical fasteners
- the electrical conductivity of the alloy may be at least 5.8 MS / m.
- Particularly preferred conductivities are at least 10 MS / m to over 13 MS / m. These values are comparable
