Taenia Calefactionis ex Mixtura Metallica 0Cr25Al5 ad Usum Fornacis FCHW-1
Mixtura Fe-Cr-Al cum resistivitate et temperatura serviendi alta quam mixtura NiCr, et etiam pretio minore.
Applicationes:Resistores electrici ferri-chromii-aluminii late ad fabricanda elementa calefactionis electrica in apparatibus domesticis et ignibus industrialibus adhibentur. Inter applicationes principales sunt ferra crassa, machinae ionizantes, calefactores aquae, formae plastificationis, ferra ad soldandum, elementa tubularia metallica obducta, et elementa cartuchos.
