Constantan Alloy - CuNi44Mn1 – High resistivity and stability of electrical resistance

Constantan 45 : technical datasheet

Download our brochure

Constantan 45 is a resistance non-magnetic alloy (Copper Nickel Manganese) designed and manufacturing by Lebronze alloys (ex. CLAL, CLAL MSX), to know more, see Bornel plant webpage.

It is available in rolled products (strip, sheets…) and drawn products (wires, rods).

Its main advantages and properties are:

  • High resistivity and stability of electrical resistance
  • Low temperature coefficient of resistance
  • Excellent resistance to oxidation and corrosion
  • Good working properties, excellent weldability and solderability
It is used in many applications such as resistors, electrical shunts, heating elements, thermocouples.

Composition and standards: ISO CuNi44Mn1.
