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