Fecralloy® Spooled Wire

Fecralloy® Spooled Wire is a continuous filament of the iron-chromium-aluminum (FeCrAl) alloy, engineered for superior oxidation resistance, high-temperature strength, and long-term stability under thermal cycling. The alloy develops a dense, adherent alumina (Al₂O₃) layer when exposed to elevated temperatures, ensuring exceptional performance in corrosive and oxidative environments up to and beyond 1300 °C. Its spooled configuration provides ease of handling, continuous feed capability, and adaptability to automated manufacturing processes. Industrial applications span heating elements in high-performance furnaces, wire-mesh catalytic substrates for automotive and industrial exhaust after-treatment, and structural frameworks in hydrogen reformers. Specific technologies benefiting from Fecralloy® Spooled Wire include Rh- and Pt-based catalyst-coated wire mesh modules for syngas production, high-efficiency emission control devices, and compact reformers for multi-fuel conversion. In research, its predictable creep-rupture behavior, oxidation kinetics, and compatibility with advanced catalytic coatings make it indispensable for developing next-generation thermal and chemical processing systems.
