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

Applications:

  • 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

 

Applications:

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

1893

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

1895

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

 

 

1957

Merging with CLAL to form Comptoir Lyon Alemand Louyot.

1967
