Lebronze alloys Group was born from the integration of different companies specializing in copper alloys, copper, nickel alloys, aluminium alloys, specialty steels, stainless steels, titanium and nickel superalloys.

Thanks to a multidisciplinary know-how, the Group provides innovative solutions to all major industries such as Aerospace, Oil & Gas, Power, Railway but also in sectors manufacturing smaller equipment and products.

Our 14 production facilities and 1,300 employees manage a unique range of metal processing technologies: continuous and semi-continuous casting, sand casting, die precision chill casting (manual, mechanized and automated), centrifugal casting, extrusion, ring rolling, hot and cold rolling, drawing, open-die forging, hot stamping, closed-die forging, cold forming, machining, non-destructive testing, etc.

The Group’s commitment is to find appropriate and optimized solutions for every sector’s requirements.

We hope that this website allows you to find answers or ideas to support your projects.

We will help you to realize these!

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.
Discover its characteristics and available forms and sizes in our technical sheet.
Composition and standards: ISO CuNi44Mn1.
