Wajer tal-manganinhija liga tar-ram-manganiż-nikil (liga CuMnNi) għall-użu f'temperatura tal-kamra. Il-liga hija kkaratterizzata minn forza elettromottiva termali baxxa ħafna (emf) meta mqabbla mar-ram.
Wajer tal-manganinhuwa tipikament użat għall-manifattura ta 'standards ta' reżistenza, resistors tal-ferita tal-wajer ta 'preċiżjoni, potenzjometri, shunts u komponenti elettriċi u elettroniċi oħra.
