He hui hao ferritic-chromium-aluminum (FeCrAl) ka uea Kanthal. ʻAʻole ia e popo a oxide paha i nā noi ʻoihana a he kūpaʻa maikaʻi loa i nā mea ʻino.

ʻOi aku ka mahana hana kiʻekiʻe o ka uea Kanthal ma mua o ka uea Nichrome. Ke hoʻohālikelike ʻia me Nichrome, ʻoi aku ka nui o ka ukana o ka ʻili, ʻoi aku ka nui o ke kū'ē ʻana, ʻoi aku ka ikaika o ka hua, a me ka haʻahaʻa o ka density. ʻOi aku ka lōʻihi o ke ola o ka uea Kanthal ma mua o 2 a 4 mau manawa ma muli o kona mau waiwai oxidation kiʻekiʻe a me ke kū'ē ʻana i nā kaiapuni sulfuric.

Kanthal A1no ka hoʻohana ʻana i nā mahana a hiki i 1400°C (2550°F). ʻO kēia ʻano Kanthal ke koho maikaʻi loa o ke kaula kū'ē no nā noi ʻoihana nui. Loaʻa iā ia kahi ikaika tensile kiʻekiʻe iki ma mua oʻO Kanthal D.

Kanthal A1ʻO ka mea maʻamau, hoʻohana ʻia ia i nā mea hoʻomehana i nā noi ʻoihana nui e like me nā umu ʻoihana (loaʻa pinepine ʻia i loko o ke aniani, keramika, mea uila, a me nā ʻoihana kila). ʻO kona resistivity kiʻekiʻe a me ka hiki ke kū i nā mea me ka ʻole o ka oxidation, ʻoiai i loko o nā lewa sulfuric a me nā lewa wela, e hana aiKanthal A1he koho kaulana i ka wā e hana ai me nā mea hoʻomehana nui. ʻOi aku ka kiʻekiʻe o ke kūpaʻa ʻana o ka uea Kanthal A1 i ka pala pulu a me ka ikaika wela a me ke kolo ma mua o Kanthal D, e lilo ia i koho kaulana no nā noi ʻoihana nui.
