Manganese copper alloy resistance alloy 0.134mm in stock 10kg price
Common name:Manganin- wire,Manganina 43, is a copper-manganese-nickel alloy (CuMnNi alloy) for use at room temperature. The alloy is characterized by very low thermal electromotive force (emf) compared to copper.
Manganin wire/strip is typically used for the manufacturing of resistance standards, precision wire wound resistors, potentiometers, shunts and other electrical and electronic components.
