High Quality Heat Resistance Alloy CuNi6 Copper Wire/CuNi Wire

CuNi alloy wire is a high-quality conductive material composed of copper (Cu) and nickel (Ni). It has good electrical conductivity, corrosion resistance and high temperature stability, and is widely used in various electrical and electronic equipment.

CuNi alloy wires are available in multiple grades, such as CuNi23, CuNi30, CuNi34, 6J8 and 6J11, each grade has different characteristics and uses. For example, CuNi23 has high resistivity and good corrosion resistance and is suitable for high-temperature heating devices and electric heating wires; while CuNi30 has lower resistivity and high mechanical strength and is suitable for high-load applications such as electric stoves and ovens.

CuNi alloy wires perform well in high temperature environments and can maintain stable electrical conductivity and mechanical strength. They are also corrosion-resistant and can withstand the attack of humidity, chemicals and corrosive gases, ensuring long-term reliable use.

Due to the excellent performance and diverse grade selection of CuNi alloy wires, they are widely used in electric heating devices, hot air fans, drying equipment, resistors, thermocouples, temperature sensors and other fields.
