CuNi30 NC035 W 2.0890 Copper Nickel Alloy High Precision Alloy Strip Rod Wire
OhmAlloy035 (Resistance heating wire and resistance wire)
(Common Name:CuNi30,NC35.Cu70Ni30)
OhmAlloy035 is a copper-nickel alloy (Cu70Ni30 alloy) with low resistivity for use at temperatures up to 350°C.
OhmAlloy035 is kind of low resistance heating alloy.It is one of the key materials of the low-voltage electrical products. It is widely used in low-voltage circuit breaker, electric blankets. Thermal overload relay, and other low-voltage electrical product.
OhmAlloy035 is typically used for low-temperature applications such as heating cables.
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.
