Constantan Wire Definition
Copper Nickel (CuNi) alloys are medium to low resistance materials typically used in applications with maximum operating temperatures up to 400°C (750°F). With low temperature coefficients of electrical resistance, resistance, and thus performance, is consistent regardless of temperature. Copper Nickel alloys mechanically boast good ductility, are easily soldered and welded, as well as have outstanding corrosion resistance. These alloys are typically used in high current applications requiring a high level of precisio
