Iron Chromium Aluminum (FeCrAl) Resistance Alloys
High resistance ferritic alloys with a maximum operating temperature of up to 2,550F. Compared to Nickel Chromium alloys, Iron Chromium Aluminum alloys are higher in resistivity, lower in density, have higher melting points, greater yield strengths, and higher maximum operating temperatures and can sustain higher surface loads. They are inherently less ductile and have lower hot strength than Nickle Chromium alloys. Owing to the formation of a tightly adhering aluminum oxide, Iron Chromium Aluminum alloys provide better resistance to oxidation in carburizing atmospheres than Nickel Chromium alloys. Due to the absence of nickel, Iron Chromium Aluminum alloys also offer greater resistance to Sulphur. They are not recommended for use in reducing atmospheres other than dry hydrogen. Iron Chromium Aluminum alloys are commonly used in high temperature heating, resistance, and related applications.
