IManganin ligama eliphawulweyo lealloyi yesiqhelo eyi-86% yobhedu, 12% yemanganese, kunye ne-2% nickel. Yaqala ukuphuhliswa nguEdward Weston ngo-1892, iphucula iConstantan yakhe (1887).
I-alloy yokumelana ne-resistivity ephakathi kunye ne-coefficent yeqondo lokushisa eliphantsi. Igophe lokuchasa / lobushushu alikho tyaba njengeecontainans kwaye azikho iipropathi zokuxhathisa umhlwa zilungile.
Ifoyile yeManganin kunye nocingo lusetyenziswa ekwenzeni izinto ezixhathisayo, ngakumbi iammetershunts, ngenxa ye-coefficient yayo yobushushu ephantse ibe yi-zero yexabiso lokumelana [1] kunye nokuzinza kwexesha elide. Iqela labachasi beManganin basebenza njengomgangatho osemthethweni we-ohm eUnited States ukusuka ku-1901 ukuya ku-1990. Ucingo lweManganin lukwasetyenziswa njengomqhubi wombane kwiinkqubo ze-cryogenic, ukunciphisa ukuhanjiswa kobushushu phakathi kwamanqaku afuna ukudityaniswa kombane.
IManganin ikwasetyenziswa kwiigeyiji kuphononongo lwamaza oxinzelelo oluphezulu (afana nalawo aveliswe kukuqhushumba kweziqhushumbisi) kuba inovakalelo oluphantsi loxinzelelo kodwa inovakalelo oluphezulu lwe-hydrostatic yoxinzelelo.
