FeCo

FeCo is an iron-cobalt soft magnetic alloy that combines high saturation magnetization with good mechanical properties, making it suitable for high-performance electromagnetic applications. It is widely used in electrical machinery, transformers, and magnetic cores where maximizing magnetic flux density in compact designs is critical. Engineers select FeCo over traditional silicon steel when applications demand superior magnetic performance at elevated temperatures or in space-constrained electromagnetic devices, though its higher cost and density typically limit it to specialized high-performance systems.
