Formula: Fe 72.8/Cr 22/Al 5/Y 0.1/Zr 0.1
Form: Disk
Material: Iron/Chromium/Aluminum (Fecralloy®)
Commodity: Alloys
Temper:
Annealed
Fecralloy® Disk is a precision-machined form of the iron-chromium-aluminum (FeCrAl) alloy, designed for applications requiring exceptional oxidation resistance, high-temperature stability, and structural integrity under cyclic thermal loading. Its ability to form a slow-growing, adherent alumina (Al₂O₃) layer at elevated temperatures provides outstanding protection in aggressive thermal and oxidative environments. The disk format offers mechanical stability and uniform thermal behavior, making it suitable for aerospace, renewable energy, and advanced thermal process industries. Specific uses include heat-resistant components in solar receiver systems, structural parts in high-temperature reactors, and protective elements in industrial gas turbines. In research, Fecralloy® Disks are used to study oxidation kinetics, high-temperature corrosion mechanisms, and heat flux management in thermal energy systems. Their combination of thermal resilience, oxidation protection, and design versatility positions them as key materials for high-performance, long-life components in demanding industrial and scientific applications.
