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.
A na-eji waya Manganin eme ihe maka imepụta ụkpụrụ nguzogide, ndị na-emegide ọnya waya ziri ezi, potentiometers,shuntna ndị ọzọeletriki na eletriki components.
