Manganin Alloy 290 Bare Wire 0.134mm 10kg for Precision Resistors

Product introduction:

Manganin wire is a precision resistance alloy composed primarily of copper (84%), manganese (12%), and nickel (4%). It is widely used in electrical and electronic applications due to its low temperature coefficient of resistance (TCR), high stability, and excellent resistance to oxidation.

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.

Common name: Manganin, Manganina 43, Alloy290
