Nicr20alsi Hlau / Karma / 6J22Wire rau Resistors
NiCr20AlSi hlau /Karma/6j22 xaim rau Resistor
Karmaalloy yog tsim los ntawm tooj liab, npib tsib xee, Aluminium thiab Hlau ua cov khoom tseem ceeb.Lub resistivity yog 2 ~ 3 npaug siab dua Manganin.Nws muaj qis dua kub coefficient ntawm tsis kam (TCR), qis thermal EMF piv rau tooj liab, zoo permanence ntawm lub sij hawm ntev thiab muaj zog tiv thaiv oxidation.Nws ua haujlwm kub ntau dua li Manganin (-60 ~ 300ºC).Nws yog tsim rau ua zoo precision kuj ntsiab thiab strain foil.
