CuNi34 is a type of resistance alloy that is composed of copper and nickel. This binary alloy has a low-temperature coefficient of resistance, making it an ideal material for manufacturing low voltage electrical components such as rheostats, shunts, and controllers. It can withstand a maximum operating temperature of 300°C, making it highly reliable for use in various applications.

One of the notable features of CuNi34 is its excellent heat coefficient, which makes it highly suitable for use in low-temperature heating cables. For instance, it is commonly used in automobile heating cushions and railway snow-melting systems. Its versatility and reliability have made it a popular choice among manufacturers of electrical components.

OhmAlloy040, also known as CuNi34 or NC040, is a copper-nickel alloy that has a low resistivity and is suitable for use at temperatures up to 350°C. This alloy is widely used as a low resistance heating material in various low-voltage electrical products, such as circuit breakers, electric blankets, and thermal overload relays.

Apart from its use in electrical products, OhmAlloy040 is also used in shipbuilding, petroleum, chemical, construction, electric power, precision instruments, medical equipment, and musical instruments. This is because it is a corrosion-resistant material that can be used to make structural parts. Additionally, some types of cupronickel have special electrical properties that make them suitable for use in resistance elements, thermocouple materials, and compensation wires.

Non-industrial cupronickel is also available and is mainly used to create decorative crafts. Overall, OhmAlloy040 is a versatile material that has a wide range of applications across various industries.
