Description

Product brief introduction

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).
