Alkrothal 14 (Resistance heat wire and resistance wire) Alkrothal 14 ndi ferritic ironchromiumaluminium alloy (FeCrAl alloy) yokhala ndi resistivity yapamwamba yoyenera kugwiritsidwa ntchito pa kutentha mpaka 1100 ° C (2010 ° F). Alkrothal 14 nthawi zambiri amagwiritsidwa ntchito ngati waya wokana magetsi pamagwiritsidwe ntchito ngati zingwe zotenthetsera.
