Definitions

  • the invention relates to a resistance alloy for an electrical resistor, in particular for a low-ohm current-measuring resistor.
  • the invention further includes a component produced therefrom and a corresponding production method.
  • Copper-manganese-nickel alloys have already been in use for a long time as materials for precision resistors, in particular for low-ohm current-measuring resistors (“shunts”).
  • An example of such a copper-manganese-nickel alloy is the resistance alloy marketed by the applicant under the trade name Manganin® (e.g. Cu 84 Ni 4 Mn 12 ) with a mass fraction of copper of 82-84%, a mass fraction of nickel of 2-4% and a mass fraction of manganese of 12-15%.
  • the known copper-manganese-nickel alloys satisfy all requirements for resistance alloys for precision resistors, such as, for example, a low temperature coefficient of the specific electrical resistance, a low thermal electromotive force against copper and a high stability of the electrical resistance over time.
  • the known copper-manganese-nickel alloys have good technological properties, in particular good working properties, allowing such copper-manganese-nickel alloys to be worked to form wires, ribbons, foils and resistor components.
  • a disadvantage of the known copper-manganese-nickel alloys is, however, the limitation to relatively low specific electrical resistances of not more than 0.5 ( ⁇ mm 2 )/m.
