CuNi alloy wire is an important conductive material composed of copper (Cu) and nickel (Ni). It has good electrical conductivity, excellent corrosion resistance and high temperature stability, and is widely used in electrical, electronic and thermal control fields.
CuNi alloy wires are available in multiple grades, such as CuNi23, CuNi30, CuNi34, 6J8 and 6J11. Different brands of CuNi alloy wires have different chemical compositions and characteristics to meet the requirements of different applications. For example, CuNi23 has higher resistivity and good corrosion resistance, making it suitable for high-temperature heating devices; while CuNi30 has lower resistivity and higher mechanical strength, making it suitable for high-load applications such as electric stoves and ovens.
CuNi alloy wire has excellent corrosion resistance and can operate stably for a long time in humid environments and corrosive gases. They are also high temperature stable and can maintain good electrical conductivity and mechanical strength under high temperature conditions. This makes CuNi alloy wire an ideal choice for electric heating devices, hot air blowers, drying equipment and temperature measurement and control devices.
