Composition: Cu 86/Mn 12/Ni 2 Form: Insulated Wire Material: Copper/Manganese/Nickel (Manganin®) Commodity: Alloys Conductor Diameter: 0.05mm Insulation: Polyester Insulation Thickness: 0.004mm
Polyester-Insulated Manganin® Wire combines the precision resistivity and thermal stability of manganin alloy with the dielectric protection and chemical resistance of a polyester coating. Known for its exceptionally low temperature coefficient of resistance, it is widely used in precision resistors, shunts, and measurement instrumentation. Industries such as aerospace, metrology, and power electronics utilize it in load cells, high-accuracy sensing devices, and stable current measurement circuits. Specific applications include precision bridge circuits, shunt resistors for calibration, and laboratory-grade thermal measurement systems. In research, it is vital for studying resistance stability, long-term drift behavior, and coating-conductor interface performance. The insulated wire’s ability to maintain electrical precision in demanding conditions makes it essential in advanced measurement technologies.
