GradeChemistryYield strengthChoose it when
Constantan 45CuMnNi630 MPaChoose it when the part carries a measured current and its resistance must stay stable with temperature. ARCAP AP4, with a close chemistry, serves elastic mechanical parts.
CuMn3CuMn
Niclal 28CuMnSn500 MPaChoose it when your shunt design calls for the lowest resistivity of the series. For a tighter temperature coefficient at a close resistivity, look at Niclal 29.
Niclal 29CuMnSn535 MPaChoose it when you need a resistivity close to Niclal 28 with a tighter temperature coefficient. For higher resistivity, move to the nickel-bearing grades from Niclal 37 upwards.
Niclal 37CuMnNi200 MPaChoose it when long-term drift is your first criterion at a mid-range resistivity. Niclal 38 shares its chemistry and adds a tighter temperature coefficient over the full rated span.
Niclal 38CuMnNi150 MPaChoose it when the part must hold its resistance over a wide temperature span, or when you need one alloy as strip and wire. Niclal 37 stays the choice for the tightest long-term drift.
Niclal 42CuMnNiChoose it when your resistor geometry calls for a resistivity between Niclal 38 and Niclal 43 and you want the strip in a choice of tempers.
Niclal 43CuMnNi570 MPaChoose it when you need this resistivity level in strip or wire with a choice of tempers. If thermal EMF against copper drives your measurement error, choose Niclal 43A.
Niclal 43ACuMnNi570 MPaChoose it when thermal EMF at copper connections limits your measurement accuracy. Niclal 43 gives the same resistivity when this criterion is secondary.
Niclal 47CuMnNiChoose it when you need a wire with more resistivity than Niclal 43A and the same low thermal EMF against copper. For the highest resistivity of the series, look at Niclal 48.
Niclal 48CuMnNi610 MPaChoose it when your design needs the highest resistivity of the series in strip form. Niclal 47 gives a slightly lower resistivity as wire, with a documented low thermal EMF against copper.
