Nicr20alki waya /Karma/ 6j22 waya wa otsutsana
Karma Alloy amapangidwa ndi mkuwa, nickel, aluminium ndi chitsulo ngati zigawo zikuluzikulu. Kuzindikira ndi 2 ~ katatu kupitilira kuposa manganin. Ili ndi kutentha kwa kutentha kwa kukana (TCR), ochepera kutentha kwa Emf motsutsana ndi mkuwa, kukhazikika kwa nthawi yayitali komanso odana ndi maxidation. Kutentha kwake kwa ntchito kumakhala kopambana kuposa manganin (-60 ~ 300ºC). Ndioyenera kusintha bwino zinthu zosanja ndi zojambulazo.
