PROBLEM TO BE SOLVED: To provide an iron - chromium - aluminum alloy for a heating wire whose strength, workability and heat resistance are simultaneously improved. SOLUTION: A ferritic Fe-Cr-Al alloy having a composition in which the amount of Cr to be added is controlled to 12 to 30 wt.%, Al to 3 to 14 wt.%, Zr to 0.01 to 1.5 wt.%, and Ti to 0.001 to 0.1 wt.%, and the balance Fe is used as a fundamental alloy. Further, Be is independently added thereto by <0.01 wt.%, or is added compositely with misch metal consisting of rare earth elements.
