CuNi Alloy Constantan Copper Nickel Resistance Wire Cuni44

CuNi alloy wire is an alloy material composed of copper (Cu) and nickel (Ni), which has good electrical conductivity and corrosion resistance. It is widely used in electrical, electronic and thermal control fields, and common grades include CuNi23, CuNi30, CuNi34, 6J8 and 6J11. Each grade has different chemical compositions and properties to suit different application needs. CuNi alloy wires perform well in high temperature and corrosive environments and can be used in various high temperature heating and measurement control applications such as electric heating devices, electric heating wires, ovens, hot air fans, drying equipment, thermocouples and temperature sensors.

CuNi alloy wire has excellent corrosion resistance, high temperature stability and reliability. They can operate stably in high temperature and corrosive environments for a long time and are suitable for various industrial and commercial fields. Different grades of CuNi alloy wires have different resistivities, current loads and mechanical strengths to meet the requirements of specific applications. Whether used in precision measurement and control applications such as electric heating devices, ovens, hot air blowers, or thermocouples and temperature sensors, CuNi alloy wire is a reliable and efficient choice.
