Description	CN30 is a copper-nickel (Cu-Ni) resistance alloy designed for electrical resistance applications requiring stable and predictable performance characteristics. The alloy provides a relatively low temperature coefficient of resistance (TCR), good workability, and good weldability, making it suitable for a wide range of electrical and electronic components. CN30 offers a balance between electrical resistivity and mechanical formability, allowing it to be used in precision resistance elements where moderate resistance values are required. Typical applications include resistors, temperature sensors, fuses, and other electrical components requiring stable resistance behavior under varying thermal conditions.
