The global demand for copper-nickel alloys in electrical applications continues to grow due to the expansion of the electronics industry and the increasing need for reliable materials in telecommunications, power generation, and automation. These alloys provide consistent performance under both normal and harsh conditions, making them indispensable in modern infrastructure.

While pure copper offers excellent conductivity, it falls short in resistance to corrosion and mechanical wear. On the other hand, adding small amounts of nickel—as in CuNi1, CuNi2, and CuNi6—enhances durability without significantly compromising electrical conductivity. This balance is one of the reasons these alloys are favored across multiple sectors.
