ʻO Alkrothal 14 ferritic ironchromiumaluminium alloy (FeCrAl alloy)
ʻO Alkrothal 14 (Uea hoʻomehana kū'ē a me ke uea kū'ē) ʻO Alkrothal 14 kahi hui hao ferritic chromiumaluminium (FeCrAl alloy) me ke kū'ē kiʻekiʻe e kūpono no ka hoʻohana ʻana i nā mahana a hiki i 1100°C (2010°F). Hoʻohana maʻamau ʻia ʻo Alkrothal 14 no ke uea kū'ē uila no nā noi e like me nā uwea hoʻomehana.
