CuNi2/CuNi6/CuNi8/CuNi10/CuNi44 Copper Nickel CuNi Alloy Electric Heating Wire

CuNi alloy wire is an alloy wire composed of copper (Cu) and nickel (Ni). It has excellent electrical conductivity, corrosion resistance and high temperature stability, and is widely used in electrical, electronic and thermal control fields.

There are several common grades of CuNi alloy wires, including CuNi23, CuNi30, CuNi34, 6J8 and 6J11. Each grade has different chemical compositions and performance characteristics to meet the needs of different applications.

CuNi23 is an alloy wire with high resistivity and good corrosion resistance. It is commonly used in high temperature heating applications such as electric heating devices, heating wires and resistors.

CuNi30 has low resistivity and good mechanical strength, making it suitable for applications requiring higher current loads and lower voltage drops, such as electric stoves, ovens and hot air blowers.

CuNi34 is an alloy wire with low resistivity and high thermal stability. It is widely used in high-temperature heating fields such as electric heating wires, drying equipment and industrial heaters.

6J8 and 6J11 are two alloy wires with special chemical composition and properties. They are commonly used in precision measurement and control applications such as thermocouples and temperature sensors.

The advantages of CuNi alloy wires include excellent corrosion resistance, high temperature stability and reliability. They are capable of stable operation for long periods of time in high temperatures and corrosive environments, making them suitable for a variety of industrial and commercial applications.
