IManganin ligama elinophawu lwe-alloy ye-86% yobhedu, i-12% ye-manganese, kunye ne-2% ye-nickel. Yaqalwa ukuphuhliswa ngu-Edward Weston ngo-1892, yaphucuka kwiConstantan yakhe (1887).

I-alloy yokumelana ene-resistivity ephakathi kunye ne-coefficient yobushushu obuphantsi. I-resistance/temperature curve ayithe tyaba njenge-constantans kwaye ayilunganga njengeempawu zokumelana nokugqwala.

Ifoyile yeManganin kunye nocingo zisetyenziswa ekwenzeni iiresistor, ingakumbi ii-ammeter shunts, ngenxa yokuba i-coefficient yayo yobushushu obuyi-zero yexabiso lokumelana [1] kunye nokuzinza kwexesha elide. Iiresistor ezininzi zeManganin zazisebenza njengomgangatho osemthethweni we-ohm eMelika ukususela ngo-1901 ukuya ku-1990.[2]Ucingo lweManganinikwasetyenziswa njengomqhubi wombane kwiinkqubo ze-cryogenic, inciphisa ukudluliselwa kobushushu phakathi kwamanqaku afuna uqhagamshelo lombane.

IManganin ikwasetyenziswa kwiigeyiji kwizifundo zamaza oxinzelelo oluphezulu (njengalawo aveliswa kukuqhuma kweziqhushumbisi) kuba inovakalelo oluphantsi loxinzelelo kodwa inovakalelo oluphezulu loxinzelelo lwe-hydrostatic.
