Manganin yog lub npe lag luam rau cov hlau sib xyaw uas feem ntau muaj 86% tooj liab, 12% manganese, thiab 2% nickel. Nws tau tsim thawj zaug los ntawm Edward Weston hauv xyoo 1892, txhim kho nws Constantan (1887).

Ib qho hlau tsis kam nrog qhov nruab nrab resistivity thiab qis kub coefficent. Qhov nkhaus tsis kam/kub tsis tiaj tus li cov constantans thiab cov khoom tiv thaiv corrosion tsis zoo.

Cov ntawv ci thiab hlau manganin siv rau hauv kev tsim cov resistors, tshwj xeeb tshaj yog ammeterkev sib hloovs, vim nws qhov kub thiab txias coefficient ntawm tus nqi tsis kam [1] thiab kev ruaj khov mus sij hawm ntev. Ntau lub Manganin resistors tau ua haujlwm raws li tus qauv kev cai lij choj rau ohm hauv Tebchaws Meskas txij li xyoo 1901 txog 1990.[2] Manganin hlau kuj tseem siv ua tus neeg coj hluav taws xob hauv cov kab ke cryogenic, txo qis kev hloov pauv cua sov ntawm cov ntsiab lus uas xav tau kev sib txuas hluav taws xob.

Manganin kuj tseem siv rau hauv cov ntsuas rau kev kawm txog cov nthwv dej siab (xws li cov uas tsim los ntawm kev tawg ntawm cov khoom tawg) vim nws muaj qhov rhiab heev qis tab sis muaj qhov rhiab heev hydrostatic siab.
