NiCr20AlSi waya/Karma/ 6j22 waya ga Resistors
Karma gami an yi shi ne da jan karfe, nickel, Aluminum da kuma Iron a matsayin manyan abubuwan da aka gyara. A resistivity ne 2 ~ 3 sau fiye da Manganin. Yana da ƙananan ƙimar juriya na juriya (TCR), ƙananan EMF mai zafi da jan ƙarfe, kyakkyawan juriya na tsayin lokaci da ƙarfi anti-oxidation. Yanayin zafin aikinsa ya fi Manganin fadi (-60 ~ 300ºC). Ya dace don yin daidaitattun abubuwa masu juriya mai kyau da tarkace.
