Aluchrom® O Spooled Wire

Aluchrom® O Spooled Wire is a high-performance iron-chromium-aluminum alloy wire optimized for resistance to oxidation and scaling at elevated temperatures, while retaining mechanical strength and formability. Supplied on spools for continuous feed in automated systems, it offers excellent dimensional stability, making it ideal for long production runs. Its primary applications are in heating element manufacturing, thermal processing equipment, and catalytic support structures in chemical industries. Specific uses include precision-wound coils for industrial furnaces, resistive heating elements in appliances and laboratory instruments, and catalyst carriers for emission control systems. Research has focused on improving high-temperature creep resistance through optimized alloying, enhancing surface oxide adherence for longer service life, and refining wire drawing processes for improved consistency in resistance and tensile properties. In scientific and industrial contexts, Aluchrom® O Spooled Wire provides an essential combination of high thermal endurance, oxidation stability, and feed reliability, enabling its integration into advanced thermal engineering and materials innovation.
