CuNi10 Copper-nickel is a copper-nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. CuNi10 is the EN chemical designation for this material. C70700 is the UNS number.
It has a moderately low tensile strength among the wrought copper-nickels in the database.
This heating resistor material is more corrosion reistant than CuNi2 und CuNi6.
We usually manufacture within a +/-5% tolerance of the electrical resistivity.
