I-Manganin yigama lokuhweba le-alloy evame ukuba ngu-86% wethusi, u-12% we-manganese, kanye no-2% we-nickel. Yaqala ukwakhiwa ngu-Edward Weston ngo-1892, yathuthuka nge-Constantan yakhe (1887).

Ingxube yokumelana enokumelana okumaphakathi kanye ne-coefficient yokushisa ephansi. Ijika lokumelana/lokushisa alisicaba njenge-constantan futhi izakhiwo zokumelana nokugqwala azizinhle kangako.

I-foil ye-manganin kanye nocingo kusetshenziswa ekwakhiweni kwama-resistor, ikakhulukazi ama-ammeter shunts, ngenxa ye-coefficient yayo yokushisa ecishe ibe yi-zero yenani lokumelana [1] kanye nokuqina kwesikhathi eside. Ama-resistor amaningana e-manganin asebenze njengendinganiso esemthethweni ye-ohm e-United States kusukela ngo-1901 kuya ku-1990.[2]Ucingo lwe-manganinisetshenziswa futhi njengomqhubi kagesi ezinhlelweni ze-cryogenic, inciphisa ukudluliselwa kokushisa phakathi kwamaphuzu adinga ukuxhumeka kukagesi.

I-Manganin isetshenziswa futhi kuma-gauge okuhlola amagagasi okushaqeka okuphezulu (njengalawo akhiqizwa ukuqhuma kweziqhumane) ngoba inokuzwela okuphansi kokucindezeleka kodwa ukuzwela okuphezulu kokucindezeleka kwe-hydrostatic.
