Cuprothal™ 49 and 49TC (Wire)

Generic Family: Copper - Wrought - Copper NickelSupplied by: Sandvik Materials Technology
Cuprothal 49 is a copper-nickel alloy (CuNi alloy) characterized by high electrical resistance, high ductility and good corrosion resistance. It is suitable for use at temperatures up to 600°C (1110°F).

Typical applications for Cuprothal 49 are temperature-stable potentiometers, industrial rheostats and electric motor starter resistances.

The combination of negligible temperature coefficient and high resistivity makes the alloy particulary suitable for the winding of precision resistors.

Cuprothal 49 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as Cuprothal 49 TC.
