I-Manganin yigama eliphawulwe ngokuhweba le-alloy ngokuvamile engu-86% wethusi, u-12% we-manganese, kanye no-2% we-nickel.Yaqala ukuthuthukiswa ngu-Edward Weston ngo-1892, ithuthukisa uConstantan (1887).

Ingxubevange yokumelana ne-resistivity emaphakathi kanye ne-coefficent yezinga lokushisa eliphansi.Ijika lokumelana/lezinga lokushisa alisicaba njengama-constantans futhi izakhiwo zokumelana nokugqwala azilungile.

Ucwecwe lweManganin nocingo kusetshenziswa ekukhiqizeni izinto eziphikisayo, ikakhulukazi ama-ammeter shunts, ngenxa ye-coefficient yayo yokushisa ecishe ibe ziro yenani lokumelana[1] kanye nokuzinza kwesikhathi eside.Izithako ezimbalwa zeManganin zasebenza njengezinga elisemthethweni le-ohm e-United States kusukela ngo-1901 kuya ku-1990.[2]I-Manganin wireiphinde isetshenziswe njengomqhubi kagesi ezinhlelweni ze-cryogenic, ukunciphisa ukudluliswa kokushisa phakathi kwamaphoyinti adinga ukuxhunywa kukagesi.

I-Manganin iphinde isetshenziswe kumageji ocwaningweni lwamagagasi okwethuka komfutho ophezulu (njengalawo akhiqizwe ekuqhunyisweni kweziqhumane) ngoba inokuzwela okuphansi kobunzima kodwa izwela ingcindezi ye-hydrostatic ephezulu.
