The present invention relates to Fe—Cr—Ar type alloys with additions to improve workability thereof, strength, and heat resistance. The present Fe—Cr—Al alloy for electric resistance wires comprises a basic alloy added with only Be of below 0.01 wt % or with both Be and misch metal composed of rare earth elements wherein the basic alloy consists of a balance element of Fe, a Cr element of 1230 wt %, an Al element of 314 wt %, a Zr element of 0.011.5 wt %, and a Ti element of 0.0010.1 wt %. The present Fe—Cr—Al type alloys remarkably improve physical properties of Fe—Cr—Al ferritic alloys, especially, workability and mechanical properties, and heating characteristic.
