Product introduction:

Common name: Manganin, Manganina 43, Alloy290

Chemical composition % and main parameters:

Manganin wire is essential in applications requiring high precision, stability, and low thermal drift. Its unique composition ensures reliable performance in demanding electrical and measurement systems.

Key Properties of Manganin Wire:

1. Low Temperature Coefficient of Resistance (TCR):

• Manganin maintains nearly constant resistance over a wide temperature range (typically ±20 ppm/°C), making it ideal for precision resistors.

2. High Resistivity (~0.47 µΩ·m):

    Allows for compact resistor designs without excessive length.

​3. Minimal Thermoelectric Voltage (vs Copper):

• Reduces errors in sensitive measurements.

4. Good Mechanical Properties:

• Can be drawn into fine wires and shaped for various applications.

Advantages of manganin product:

• Precision resistors (shunts, decade boxes, calibration standards)

• Current sensing (ammeters, power measurement)

• Strain gauges & sensors (due to stable resistance under stress)

• Laboratory and industrial instruments requiring stable resistance
