Manganin ndi dzina lachizindikiro cha aloyi ya 86% yamkuwa, 12% manganese, ndi 2% nickel. Idapangidwa koyamba ndi Edward Weston mu 1892, ndikuwongolera pa Constantan wake (1887).

Aloyi yotsutsa yokhala ndi resistivity yapakatikati komanso kutentha kocheperako. Kukaniza / kutentha kumapindikira silathyathyathya ngati ma constantans komanso kukana kwa dzimbiri sikwabwino.

Manganin zojambulazo ndi waya amagwiritsidwa ntchito popanga resistors, makamaka ammetershunts, chifukwa cha kutentha kwake pafupifupi zero kokwanira [1] komanso kukhazikika kwanthawi yayitali. Otsutsa angapo a Manganin adagwira ntchito ngati mulingo walamulo wa ohm ku United States kuyambira 1901 mpaka 1990.[2] Waya wa Manganin amagwiritsidwanso ntchito ngati kondakitala wamagetsi mumakina a cryogenic, kuchepetsa kutentha kwapakati pakati pa mfundo zomwe zimafunikira kulumikizidwa kwamagetsi.

Manganin amagwiritsidwanso ntchito poyesa mafunde amphamvu kwambiri (monga omwe amapangidwa kuchokera kuphulika kwa zophulika) chifukwa ali ndi mphamvu yocheperako koma imakhudzidwa kwambiri ndi hydrostatic pressure sensitivity.
