Nicr20ysi Waya /Karma/ 68J22 Waya ga Masu Tsayayya
Karma alloy ya yi jan ƙarfe, nickel, aluminium da baƙin ƙarfe a matsayin manyan abubuwan da aka samu. Risiya shine 2 ~ sau 3 sama da maniganin. Yana da ƙananan yawan yawan zafin jiki na juriya (TCR), ƙananan Thermal Emf na ƙarfe mai tsayi na dogon lokaci da hadawa mai ƙarfi. Yankin zafin jiki yana fadi fiye da Mancganin (-60 ~ 300ºC). Ya dace domin yin kyakkyawan yanayin abubuwan juriya da tsare-tsaren halitta.
