Alloy 290/ C17200 nickel-tooj ​​liab alloy hlau rau potentiometers / shunts

Lub precision tsis kam alloy MANGANIN yog tshwj xeeb tshaj yog cov yam ntxwv ntawm qhov kub tsis tshua muaj coefficient ntawm 20 thiab 50 ° C nrog cov duab parabolic ntawm R (T) nkhaus, lub sij hawm ntev stability ntawm hluav taws xob tsis kam, tsis tshua muaj thermal EMF piv rau tooj liab thiab cov khoom ua haujlwm zoo.
Txawm li cas los xij, ntau dua thermal loads hauv qhov chaw uas tsis yog oxidizing tuaj yeem ua tau. Thaum siv rau precision resistors nrog siab tshaj qhov yuav tsum tau, cov resistors yuav tsum tau ua tib zoo stabilized thiab daim ntawv thov kub yuav tsum tsis txhob ntau tshaj 60 ° C. Tshaj qhov siab tshaj plaws ua haujlwm kub hauv huab cua tuaj yeem ua rau muaj kev tiv thaiv drift tsim los ntawm cov txheej txheem oxidizing.Yog li, kev ruaj ntseg ntev tuaj yeem cuam tshuam tsis zoo. Yog li ntawd, lub resistivity nrog rau qhov kub coefficient ntawm hluav taws xob kuj yuav hloov me ntsis. Nws kuj yog siv los ua cov khoom siv uas tsis tshua muaj nqi rau cov nyiaj solder rau cov hlau tawv tawv.

Specifications
manganin hlau / CuMn12Ni2 Hlau siv hauv rheostats, resistors, shunt thiab lwm yam manganin hlau 0.08mm txog 10mm 6J13, 6J12, 6J11 6J8
Manganin hlau (cupro-manganese hlau) yog lub npe lag luam rau cov hlau alloy feem ntau 86% tooj liab, 12% manganese, thiab 2-5% npib tsib xee.
Manganin hlau thiab ntawv ci yog siv nyob rau hauv lub manufactue ntawm resistor, tshwj xeeb tshaj yog ammeter shunts, vim hais tias ntawm nws cirtually xoom kub cofficient ntawm resintance tus nqi thiab ntev lub sij hawm stability.

Kev siv ntawm Manganin

Manganin ntawv ci thiab hlau yog siv rau hauv kev tsim cov resistor, tshwj xeeb tshaj yog ammeter shunt, vim nws zoo li xoom kub coefficient ntawm cov nqi kuj thiab lub sij hawm ntev stability.
Cov tooj liab-raws li tsis tshua muaj hluav taws xob cua sov alloy yog dav siv nyob rau hauv low-voltage circuit breaker, thermal overload relay, thiab lwm yam khoom siv hluav taws xob tsawg. Nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob tsawg. Cov ntaub ntawv tsim los ntawm peb lub tuam txhab muaj cov yam ntxwv ntawm kev ua haujlwm zoo sib xws thiab kev ruaj ntseg zoo dua. Peb tuaj yeem muab txhua yam ntawm cov hlau puag ncig, tiaj tus thiab cov ntaub ntawv.
