Description	CN49 is a copper-nickel (Cu-Ni) resistance alloy designed for electrical and electronic applications requiring stable resistance characteristics across varying temperatures. The alloy offers a relatively low temperature coefficient of resistance (TCR), good mechanical workability, and good weldability, making it suitable for precision resistance components and general electrical applications. CN49 provides a balance between electrical resistivity and thermal stability, enabling reliable performance in environments where temperature fluctuations are present. Typical applications include resistors, temperature sensors, fuses, and other electrical components requiring consistent resistance behavior under thermal cycling conditions.
