Makala:
Na maisha marefu ya huduma.Haki juu ya haraka.High Ufanisi wa mafuta.Memperature umoja. Inaweza kutumia wima. Wakati wa kutumiwa katika voltage iliyokadiriwa, hakuna jambo tete.it ni waya wa joto wa kinga ya mazingira. Na mbadala kwa waya wa gharama kubwa wa nichrome.
Aloi za fecral zinaonyeshwa na upinzani bora wa oxidation na utulivu mzuri wa fomu husababisha maisha marefu.
Kawaida hutumiwa katika vitu vya kupokanzwa umeme katika vifaa vya viwandani na vifaa vya nyumbani.
Aloi ya Fe-Cr-Al na joto la juu na joto la huduma kuliko ile kwa aloi ya NICR na pia ina bei ya chini.
Eneo la maombi
Bidhaa zetu hutumiwa sana katika vifaa vya matibabu ya joto, sehemu za auto, utengenezaji wa chuma na chuma,
Sekta ya aluminium, vifaa vya madini, vifaa vya petroli, mashine za glasi, mashine za kauri,
Mashine ya chakula, mashine za dawa, na tasnia ya uhandisi wa nguvu.
