Hlau manganin yog ib qho hlau tooj liab-manganese-nickel (CuMnNi alloy) rau kev siv ntawm chav tsev kub. Cov hlau no yog tus cwj pwm los ntawm lub zog thermal electromotive qis heev (emf) piv rau tooj liab.
Cov hlau manganin feem ntau yog siv rau kev tsim cov qauv tsis kam, cov hlau precision qhov txhab resistors, potentiometers,kev sib hloovs thiab lwm yam hluav taws xob thiabcov khoom siv hluav taws xob.

Cov Lus Qhia Tshwj Xeeb
manganin hlau/CuMn12Ni2 Hlau siv hauv rheostats, resistors, shunt thiab lwm yam manganin hlau 0.08mm txog 10mm 6J13, 6J12, 6J11 6J8
Hlau manganin (cupro-manganese hlau) yog lub npe lag luam rau cov hlau sib xyaw ntawm feem ntau 86% tooj liab, 12% manganese, thiab 2-5% nickel.
Cov hlau manganin thiab ntawv ci yog siv rau hauv kev tsim khoom ntawm resistor, tshwj xeeb tshaj yog ammeter shunts, vim nws qhov kub thiab txias tsis zoo ntawm cov nqi resistance thiab kev ruaj khov ntev.

Kev siv Manganin

Cov ntawv ci thiab hlau manganin yog siv rau hauv kev tsim cov resistor, Tshwj xeeb tshaj yog ammeter shunt, vim nws qhov kub thiab txias coefficient ntawm tus nqi tsis kam thiab kev ruaj khov ntev.
Cov hlau ua los ntawm tooj liab uas tsis tshua muaj zog kub yog siv dav hauv cov khoom siv hluav taws xob tsawg, cov khoom siv thermal overload relay, thiab lwm yam khoom siv hluav taws xob tsawg. Nws yog ib qho ntawm cov khoom siv tseem ceeb ntawm cov khoom siv hluav taws xob tsawg. Cov khoom siv uas peb lub tuam txhab tsim tawm muaj cov yam ntxwv ntawm kev tiv taus zoo thiab ruaj khov. Peb tuaj yeem muab txhua yam hlau puag ncig, hlau tiaj tus thiab hlau ntawv.
