Constantan Konstantan CuNi44 Copper Nickel wire 1.0mm for jump wire
Huona Alloys is a copper - nickel alloy (Cu56Ni44 alloy)
characterized by high electrical resistance, high ductility and
good corrosion resistance. It is suitable for use at temperatures
up to 400°C. Typical applications for Huona Alloys are temperature
- stable potentiometers, industrial rheostats and electric motor
starter resistances.
The combination of negligible temperature coefficient and high
resistivity makes the alloy particularly suitable for the winding
of precision resistors.
Huona Alloys is manufactured from electrolytic copper and pure
nickel. In finer wire sizes the alloy is designated as Huona
Alloys(Thermocouple).
