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 11 production facilities and 850 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!

CLAL (2)

From casting to hot rolling and the different stages of cold forming.

Bornel facility (Ex-CLAL) is recognized internationally for its unique experience in the elaboration and transformation of rolled products and dawn products, notably copper alloys and nickel alloys.


Specialty of the site :

continuous casting,

semi-continuous casting,







Examples of products:



Niclafor 1000® :


Niclal 29

Niclal29 is a Copper Manganese Tin alloy “CuMnSn” with high precision resistance and resistance stability. It is designed and manufactured by Lebronze alloys (ex. CLAL, CLAL MSX).

Niclal29 is characterized by parabolic relation between Resistance and Temperature. For some applications, the maximum of the parabola (peak temperature) is kept near room temperature by controlling chemical composition, minimizing the effects of small changes in ambient temperature. Temperature Coefficient of resistance (TCR) of Niclal29 usually less than +/-10 ppm/°C for an interval of 20 °C on either side of the peak.

Alloy properties:

  • High stability of electrical resistance
  • Good working properties
  • Excellent weldability/solderability


  • Precision resistors
  • Electrical shunts

Niclal 43

Niclal43 is a Copper Manganese Nickel alloy “CuMnNi” with high precision resistance and resistance stability. It is designed and manufactured by Lebronze alloys (ex. CLAL, CLAL MSX).

Alloy properties:

  • Precision resistance alloy (43 μohm.cm)
  • Moderate resistivity
  • Low temperature coefficient of resistance versus Copper
  • Low thermal EMF versus Copper



  • Precision resistors
  • Electrical shunts in electricity meter
  • Electrical shunts in DC ammeter




History of the site:


M. Emile LOUYOT set up the company in Paris.


The Société Française des Métaux (SFM) acquires the ALPHEN plant.


LOUYOT Company moves in Bornel through the acquisition of the S.F.M plant.




Merging with CLAL to form Comptoir Lyon Alemand Louyot.


Hot rolling process hall construction.


Construction of a shearing workshop.


Construction of the new hot rolling mill.


CLAL becomes a subsidiary of the Group Fimalac SA under the name CLAL-MSX.


CLAL France and its subsidiaries are taken over by Lebronze alloys Group.  In July, CLAL France merges with Le Bronze Industriel.

On December 1rst, all French companies of the Group merge and are renamed into Lebronze alloys.
