Manganin waa magac ganacsi oo calaamad u ah daawaha sida caadiga ah 86% copper, 12% manganese, iyo 2% nikkel.Waxaa markii ugu horreysay sameeyay Edward Weston 1892-kii, isaga oo kor u qaaday Constantan (1887).

Daawaha iska caabin ah oo leh iska caabin dhexdhexaad ah iyo heerkul hooseeya oo isku habboon.Qalooca caabbinta/heerkulka maaha mid siman sida joogtada ah mana aha kuwa iska caabbinta daxalka sida wanaagsan.

Manganin foil iyo silig waxaa loo isticmaalaa soo saarista iska caabiyeyaasha, gaar ahaan shunts-beeraha ammeter-ka, sababtoo ah isku-dhafka heerkulka eber ee qiimaha iska caabinta [1] iyo xasilloonida muddada dheer.Dhowr iska caabiyeyaasha Manganin waxay u adeegeen sidii halbeegga sharciga ah ee ohm gudaha Mareykanka laga bilaabo 1901 ilaa 1990.[2]Manganin siligWaxa kale oo loo isticmaalaa sidii kirishbooyeeyaha korantada ee nidaamyada cryogenic, yaraynta kulaylka u dhexeeya dhibcaha u baahan isku xirka korantada.

Manganin waxa kale oo loo isticmaalaa qiyaasaha daraasaadka mowjadaha shoogga ee cadaadiska sarreeya (sida kuwa ka dhasha qarxinta walxaha qarxa) sababtoo ah waxay leedahay dareen cadaadis hooseeya laakiin dareenka cadaadiska hydrostatic sare.
