Manganin yog lub npe lag luam rau cov hlau alloy feem ntau 86% tooj liab, 12% manganese, thiab 2% npib tsib xee. Nws yog thawj zaug tsim los ntawm Edward Weston hauv 1892, txhim kho nws Constantan (1887).

Ib qho tsis kam alloy nrog nruab nrab resistivity thiab qis kub coefficient. Qhov kev tiv thaiv / qhov kub thiab txias tsis yog tiaj tus li cov constantans los yog cov khoom tiv thaiv corrosion zoo li.

Manganin ntawv ci thiab hlau yog siv los tsim cov resistors, tshwj xeeb yog ammetershunts, vim hais tias ntawm nws zoo li xoom kub coefficient ntawm kuj tus nqi [1] thiab lub sij hawm ntev stability. Ob peb Manganin resistors tau txais kev cai lij choj rau ohm hauv Tebchaws Meskas los ntawm 1901 txog 1990.[2] Manganin hlau kuj tseem siv los ua cov khoom siv hluav taws xob hauv cov tshuab cryogenic, txo cov cua sov hloov ntawm cov ntsiab lus uas xav tau kev sib txuas hluav taws xob.

Manganin kuj tseem siv tau rau hauv cov ntsuas rau kev tshawb fawb txog kev kub ntxhov siab tsis muaj zog (xws li cov khoom tsim los ntawm kev tawg ntawm cov khoom tawg) vim tias nws muaj qhov tsis tshua muaj siab tab sis siab hydrostatic siab rhiab heev.
