Definitions

• CCS copper clad steel
• CCA copper clad aluminum
• ACS aluminum clad steel
• ICN iron clad nickel
• Dumet composite copper clad FeNi42 / 47
• CCA composite wires also have the disadvantage of low strength.
• the invention is therefore based on the object to provide a metal composite wire available that meets the requirements set as well as possible.
• composite wires can be produced which meet the requirements mentioned above. That is, this alloy and second layer (preferably copper layer) can be coordinated so that both the tensile strength, the bending fatigue strength and the conductivity are sufficiently high. It can also be made a good connection between the individual layers, which is important for the strength properties of the composite wire.
• the alloy constituents By choosing the alloy constituents, it is also possible to achieve high corrosion resistance in corrosive, for example saline, aqueous media, and that is because not only the two individual components are inherently stable, but moreover both components in the electrochemical series close to each other are found, which is why in the presence of electrolytes, the susceptibility to corrosion is very low.
• a layer of the non-ferrous metal alloy is an inner layer and an outer layer is a copper layer.
• the area fraction of the layer of Cu is preferably 20-80%, preferably 65-70%, of the total cross-sectional area of the composite wire. With a Cu area ratio in these ranges, both favorable mechanical properties and electrical properties can be achieved and, as mentioned above, a good further processability of the composite wire is given.
• the metallic composite wire according to the invention has a round cross-section, since this cross-sectional shape is used very frequently.
• the core layer is made of the non-ferrous metal alloy and the outermost layer is made of copper. With such a composite wire, the demands made can meet particularly well.
• the metallic composite wire according to the invention is preferably used in signal lines in motor vehicle construction and therefore preferably has a cross-sectional area of 0.05 to 0.5 mm 2.
• the non-ferrous metal alloy preferably contains the following components in the proportions indicated below (in% by weight): Ni 3.0% to 28% Fe 1.5% to 15% Mn 1.5% to 10% Cu Rest, wherein the sum of the selected proportions 100% by weight, since an alloy with said constituents in the above-mentioned areas particularly well meets the requirements initially stated.
• the non-ferrous metal alloy particularly preferably contains the following ingredients in the proportions indicated below (in weight%): Ni 5.0% to 20% Fe 2.0% to 12% Mn 2.0% to 8th % Cu Rest, the sum of the proportions chosen being 100% by weight.
• the non-ferrous metal alloy most preferably contains the following ingredients in the proportions indicated below (in weight%): Ni 6.0% to 13% Fe 2.1% to 8th % Mn 2.5 % to 6% Cu rest the sum of the proportions chosen being 100% by weight.
• the non-ferrous metal alloy contains the following constituents in the proportions indicated below (in% by weight): Ni 7.620% Fe 3.570% Mn 3.760% C 0.002% Si 0.023% mg 0.015% Ti 0.310% S 0.007% P 0.002% Cu 84.691%.
• This can be achieved by either stationary annealing (T 200 - 500 ° C) or by in-line annealing (conductive, inductive, etc.) at diameter-dependent speeds and temperatures, both in a non-oxidizing atmosphere.
• a ⁇ 200 12 % ,
• the elongation at break correlates with the bending fatigue strength
• the latter can also be adjusted in a targeted manner in such composite wires with hard and soft components.
• the 0.40 and 0.50 mm diameter bare composite wires have a high flex life of significantly> 300 flexures (180 °, over 10 mm mandrel, at 200 g load weight, 60 cycles per sec Minute) until breakage.
• an inner component can be annealed, while the others remain hard as long as the recrystallization temperatures of the components sufficiently differ.
• the composite wire according to the above example has a resistivity of 0.026 Ohm mm 2 / m, which corresponds to approximately 38.5 SE (Siemens units) and thus about 65% IACS, so about 65% of the conductivity of copper.
• the compound wire with components according to the above example in the hard inside variant can, because of this combination of its corrosive, electrical and mechanical properties, e.g. be used as conductors in cables and lines, preferably where signal currents (low current) are to be routed, and where it can not be ruled out that the conductor in the contact area is exposed to aggressive media (for example salt spray water).
• aggressive media for example salt spray water
• this composite wire is not only ductile or solid, but combines both properties, it is also suitable as a single conductor to replace a copper strand of larger cross-section, while maintaining the required conductivity, ductile properties (such as bending fatigue strength) and comparable strength / yield strength compared to a larger diameter Cu strand.
• such a composite wire with an outside diameter of 0.50 mm / cross-section 0.22 mm 2 is suitable for replacing a copper strand with a total cross-section of 0.50 mm 2, an outside diameter of 0.40 mm / cross-section 0.13 mm 2 or even one with an outside diameter of 0.30 mm / cross-section
• 0.07 mm 2 can replace a copper strand with a total cross section of 0.35 mm2.
