Electric Current Measure Manganin Shunts

Advantages of Manganin Copper Characteristics in Applications

Low Temperature Coefficient of Resistance (TCR)

One of the most important characteristics of Manganin is its low TCR (~15 ppm/°C), which ensures resistance values remain stable despite ambient temperature fluctuations. This is critical in energy monitoring and automotive systems where precise current measurement is essential over a wide temperature range.

High Stability and Long-Term Accuracy

Unlike pure copper, which changes resistance significantly with heat, Manganin maintains a steady resistivity over time and under load. This ensures long-term accuracy in electric current sensing and avoids signal drift.

Excellent Thermal EMF Characteristics

Manganin generates minimal thermal electromotive force when in contact with copper, reducing parasitic voltage and ensuring a cleaner, more accurate current signal.

Low Resistivity and High Heat Dissipation

Although it has low resistivity compared to some alloys, it efficiently dissipates heat generated during current flow, which protects the system from overload or thermal runaway.

Good Machinability and Weldability

Manganin is compatible with precision stamping, spot welding, and resistance brazing processes, allowing manufacturers to produce stable and compact assemblies for both standard and Magnetic Shunt Customized designs.

Advanced Spot Welding Technology

Precision Joints with Minimal Heat Impact

Using servo-controlled welders with 0.1ms timing resolution, we create weld points with diameters of 1.5-3mm, localized to avoid overheating the manganin body. This preserves the alloy's electrical properties while achieving shear strengths >50N per weld point-critical for Shunt Terminal for Magnetic Latching Relay, where vibrations could otherwise loosen connections.

Consistency in High-Volume Production

Automated welders with vision systems monitor each joint in real time, adjusting current and pressure to compensate for minor material variations. This ensures uniform resistance (<50μΩ per joint) across thousands of units, a necessity for automotive clients ordering 100,000+ Copper Manganin Shunts for EV battery management systems.

Compatibility with Complex Geometries

Our technology handles intricate shapes, such as shunts with offset terminals or stepped profiles, common in Magnetic Shunt Customized designs for aerospace relays. Unlike manual soldering, spot welding avoids flux residue and ensures repeatable results, even for shunts with tight clearances.
