I-Alkrothal 14 (ukumelana nokushisa kwentambo kanye nokumelana ne-wire) i-alkrothal 14 yi-Ferritic ironchromiuminium alloy (fecal alloy) enokumelana okuphezulu efanelekile ukusetshenziswa kumazinga okushisa afinyelela ku-1100 ° C (2010 ° F). I-Alkrothal 14 imvamisa isetshenziselwa ukumelana ngogesi kwezinsiza ezifana nezintambo zokushisa.
