Composition: Cu 86/Mn 12/Ni 2 Form: Insulated Wire Material: Copper/Manganese/Nickel (Manganin®) Commodity: Alloys Insulation: Polyimide
Polyimide-Insulated Manganin® Wire merges the low temperature coefficient of resistance and long-term stability of manganin alloy with the high thermal endurance and chemical resistance of polyimide insulation. It is widely used in precision resistors, shunts, and metrology instrumentation requiring exceptional measurement stability over time and temperature variations. Industries such as aerospace, scientific instrumentation, and power electronics employ it in calibration devices, laboratory-grade resistance standards, and high-precision current sensing systems. Specific uses include shunt resistors in spacecraft power systems, bridge circuits for instrumentation, and thermal stability studies. In research, it is central to investigations on resistive drift, insulation stability at elevated temperatures, and alloy-coating adhesion under environmental stress. The insulated wire’s precision and resilience make it a cornerstone in advanced measurement applications.
