Kipengele:
Pamoja na maisha ya muda mrefu ya huduma. Inapasha joto haraka. Ufanisi wa juu wa joto. Usawa wa joto. Inaweza kutumia wima. Inapotumiwa katika voltage iliyokadiriwa, hakuna jambo tete. Ni ulinzi wa mazingira waya wa kupokanzwa umeme. Na mbadala wa waya wa gharama ya nichrome.Inaweza kubinafsishwa kulingana na mahitaji ya mteja
Aloi za FeCrAl zina sifa ya upinzani bora wa oxidation na uthabiti mzuri sana wa fomu unaosababisha maisha ya muda mrefu.
Kwa kawaida hutumiwa katika vipengele vya kupokanzwa umeme katika tanuu za viwanda na vifaa vya nyumbani.
Aloi ya Fe-Cr-Al yenye uwezo wa juu wa kustahimili uwezo na halijoto ya kuhudumia kuliko ile ya aloi ya NiCr na pia ina bei ya chini.
Eneo la maombi
Bidhaa zetu hutumiwa sana katika vifaa vya matibabu ya joto, sehemu za magari, utengenezaji wa chuma na chuma,
tasnia ya alumini, vifaa vya metallurgiska, vifaa vya petrochemical, mashine za glasi, mashine za kauri,
mashine za chakula, mashine za dawa, na tasnia ya uhandisi wa nguvu.
