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.
- nickel-chromium alloys for example, are known, but these likewise exhibit various disadvantages.
- nickel-chromium alloys are mostly substantially more expensive than copper-manganese-nickel alloys.
- nickel-chromium alloys are more difficult to handle in many respects from the production point of view.
- the hot workability of nickel-chromium alloys is relatively poor, and complex heat treatment processes are necessary in order to establish specific electro-physical material properties.
- the working temperatures in the melting process are about 500K higher in the case of nickel-chromium alloys than in the case of copper-manganese-nickel alloys, which leads to higher energy costs and material wear of the working equipment.
- the good acid resistance of nickel-chromium alloys which is otherwise desirable, gives rise to major problems in the production of resistor structures by etching and makes the removal by pickling of oxides caused by heat treatment a complex and non-hazardous manufacturing step.
- the copper-manganese-nickel-aluminum alloy 29-5-1 which has a specific electrical resistance of 1 ( ⁇ mm 2 )/m and thereby satisfies the requirement for a low temperature coefficient of the specific electrical resistance.
- this resistance alloy has a high thermal electromotive force against copper at 20° C. of +3 ⁇ V/K, resulting in high fault currents which render this alloy unsuitable for precise measurement applications.
