NiCr20AlSi silig/Karma/ 6j22 silig ee Resistors
Daawaha Karma waxa uu ka kooban yahay naxaas, nikkel, Aluminium iyo Iron sida qaybaha ugu muhiimsan. Iska caabintu waa 2 ~ 3 jeer ka sarreeya Manganin. Waxay leedahay heerkulka hoose ee iska caabinta (TCR), kulaylka hoose ee EMF iyo naxaas, joogtaynta wanaagsan ee iska caabbinta muddo dheer iyo anti-oxidation xooggan. Heerkulka shaqadeeda ayaa ka ballaaran Manganin (-60 ~ 300ºC). Waxay ku habboon tahay samaynta walxaha iska caabbinta saxda ah ee saxda ah iyo biilka cadaadiska.
