OhmAlloy030(Resistance heating wire and resistance wire)
(Common Name:CuNi23,NC30,Curpothal30)
OhmAlloy030 is a copper-nickel alloy (Cu77Ni23 alloy) with low resistivity for use at temperatures up to 300°C.
OhmAlloy030 is typically used for applications such as heating cables, fuses, shunts, resistors and various types of controllers.
The addition of nickel to pure copper can significantly improve the strength, corrosion resistance, hardness, electrical resistance and thermoelectricity, and reduce the temperature coefficient of resistivity. Therefore, compared with other copper alloys, the mechanical and physical properties of cupronickel are extremely good, with good ductility, high hardness, beautiful color, corrosion resistance and deep drawing performance.
It is widely used as corrosion-resistant structural parts in shipbuilding, petroleum, chemical, construction, electric power, precision instruments, medical equipment, musical instruments and other departments. Some cupronickel has special electrical properties, which can be used to make resistance elements, thermocouple materials and compensation wires. Non-industrial cupronickel is mainly used to make decorative crafts.
