0.015mm Manganese Copper Alloy For Wheatstone Bridges
Manganese Copper Alloy 6J12 0.015mm Foil /Strip For Wheatstone Bridges
1. Description
Manganin is a copper-manganese-nickel resistance alloy. It combines all the properties required of a precision electrical resistance alloy such as high resistivity, low temperature coefficient of resistance, very low thermal effect against copper and good performance of electrical resistance over long periods of time.

Shunt Manganin widely used for Shunt resistor with the highest requirements, shunt manganin has been used in precision built electrical components such as Wheatstone bridges, decade boxes, voltage drivers, potentiometers and resistance standards.
Tankii's manganin/constantan in our company belongs to copper-manganese alloy. Compared with traditional manganin/constantan, it has high dimensional accuracy, excellent processability, stable resistivity, and its material utilization could increase by more than 50% in the manufacturing process.
Manganin has good piezoresistive effect and is widely used in pressure measurement in high temperature and high pressure environments such as detonation, high-speed impact, dynamic fracture, new material synthesis and so on.
Tankii can supply foil, strip, sheet, wire, ribbon etc.
2. Characteristics:
| Small temperature coefficient of resistance, |
| Low identical electromotive force |
| Special excellent resistance stability |
| Good welding performance |
| Good machining performance, |
In the electrical and instrument measuring technology as well as the benchmark unit with a resistor is widely used.
Manganese copper alloy has good welding performance and machining performance, can form the fine silk, rolling piece, foil, but poor corrosion resistance and oxidation resistance.
