ARMCO® Soft Ingot Iron Foil (Light Tight) is a high-purity, ultra-low carbon iron material, engineered for precise applications including light-sensitive environments and where surface consistency and integrity is critical. Its high magnetic permeability and low coercivity make it ideal for magnetic shielding in optical experiments, cryogenic systems, and UHV setups, where controlling light interference is crucial. The foil’s uniform composition ensures consistent magnetic behavior while preventing light contamination, essential for beamline applications and nanoscale measurements. It also offers mechanical flexibility, making it suitable for custom forming in sensitive instrumentation. Commonly used in spintronics research, this foil is designed to meet the rigorous demands of cutting-edge research in experimental physics and materials science.
