CuMn12Ni4 Alloy
Introduction
Manganese copper alloy used for shunt can be used at room temperature. This alloy is characterized
by low electromotive force.
| Alloy | Type | Size | ||
| Manganin43W | Round wire | D=0.03mm~8mm |
|
|
| Manganin43R | Flat wire | W=0.4~40 | T=0.03~2.9mm |
|
| Manganin43S | Strip | W=8~200mm | T=0.1~3.0 |
|
| Manganin43F | Foil | W=6~120mm | T=0.003~0.1 |
|
| Manganin43B | Rod | Dia=8~100mm | L=50~1000 |
|
Application
Manganese copper alloy is widely used in shunt resistor with high requirement, and built-in
precision electrical element, like: electric bridge, potentiometer, etc.
