Description

Constantan 45 is a resistance non-magnetic alloy (Copper Nickel Manganese) designed and manufacturing by Lebronze alloys (ex. CLAL, CLAL MSX). 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
  • Equivalent Materials

    This material data has been provided by Lebronze Alloys.

    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
