NiCr20AlSi terata/Karma/6j22 terata bakeng sa Resistors
Karma alloy e entsoe ka koporo, nickel, Aluminium le Iron e le likarolo tsa mantlha. The resistivity ke makhetlo a 2 ~ 3 ho feta Manganin. E na le mocheso o tlase oa mocheso oa ho hanyetsa (TCR), mocheso o tlase oa EMF khahlanong le koporo, ho hanyetsa ka nako e telele nako e telele le anti-oxidation e matla. Mocheso oa eona oa ho sebetsa o pharalletse ho feta Manganin (-60 ~ 300ºC). E loketse ho etsa lintho tse hanyetsanang hantle ka nepo le foil ea khatello.
