Manganin ndi dzina lodziwika bwino la alloy ya 86% yamkuwa, 12% ya manganese, ndi 2% ya nickel. Inapangidwa koyamba ndi Edward Weston mu 1892, ndipo inasintha dzina lake la Constantan (1887).

Chotsukira cholimba chomwe chili ndi mphamvu yochepetsera kutentha komanso mphamvu yotsika ya kutentha. Chotsukira/kutentha kwake si chathyathyathya ngati ma constantan ndipo mphamvu zake zopewera dzimbiri sizili bwino.

Manganin foil ndi waya zimagwiritsidwa ntchito popanga ma resistors, makamaka ma ammeter shunts, chifukwa cha kutentha kwake pafupifupi zero temperature coefficient of resistance value [1] komanso kukhazikika kwa nthawi yayitali. Ma Manganin resistors angapo anali ngati muyezo wovomerezeka wa ohm ku United States kuyambira 1901 mpaka 1990.[2]Waya wa Manganinimagwiritsidwanso ntchito ngati chowongolera magetsi m'makina a cryogenic, kuchepetsa kusamutsa kutentha pakati pa malo omwe amafunika kulumikizana ndi magetsi.

Manganin imagwiritsidwanso ntchito mu ma gauge pofufuza mafunde amphamvu (monga omwe amapangidwa ndi kuphulika kwa mabomba) chifukwa imakhala ndi mphamvu yochepa koma mphamvu zambiri za hydrostatic pressure.
