NiCr20AlSi uaea/Karma/6j22 uaea mo Resistors
Karma alloy e faia i le kopa, nickel, Alumini ma Umea e avea ma vaega autu. O le resistivity e 2 ~ 3 taimi maualuga atu nai lo Manganin. O loʻo i ai le maualalo o le vevela o le teteʻe (TCR), maualalo le vevela EMF versus kopa, tumau lelei o le tetee mo se vaitaimi umi ma le malosi anti-oxidation. O lona tulaga vevela galue e lautele atu nai lo Manganin (-60 ~ 300ºC). E fetaui lelei mo le faia o elemene sa'o sa'o lelei ma fa'ama'i pepa.
