Manganin wayabụ ọla kọpa-manganese-nickel alloy (CuMnNi alloy) maka ojiji na ụlọ okpomọkụ. Ihe e ji mara alloy ahụ bụ ike ọkụ eletrik dị ala (emf) ma e jiri ya tụnyere ọla kọpa.
Manganin wayaa na-ejikarị maka imepụta ụkpụrụ nguzogide, ndị na-emegide ọnya waya ziri ezi, potentiometers,shuntna ndị ọzọeletriki na eletriki components.

Nkọwapụta
manganin waya / CuMn12Ni2 Waya eji na rheostats, resistors, shunt wdg manganin waya 0.08mm ka 10mm 6J13, 6J12, 6J11 6J8
waya manganin ( cupro-manganese waya) bụ aha ụghalaahịa maka ihe alloy nke na-abụkarị 86% ọla kọpa, 12% manganese, na 2-5% nickel.
A na-eji waya Manganin na foil na-emepụta ihe na-emepụta resistor, karịsịa ammeter shunts, n'ihi na ọ naghị enwe okpomọkụ nke gburugburu ya nke uru resintance na nkwụsi ike ogologo oge.
