Researchers Developed New High-Performance Magnetic Alloy
The FeCoNiCr alloy offers improved magnetic and electrical properties for power electronic components.
Updated on Oct. 5, 2026 in Materials Science
Scientists have created a novel FeCoNiCr medium-entropy alloy using binder jetting and in-situ carbon doping. This new material demonstrates significant potential for power electronics by exhibiting high electrical resistivity and low coercivity.
Why it matters
This manufacturing strategy addresses the challenge of combining superior magnetic performance with the ability to create complex shapes for modern electrical systems. It provides a pathway to minimize core energy loss in high-frequency applications.
The alloy utilizes binder decomposition to incorporate carbon into the FCC lattice during high-temperature sintering, resulting in coarse, equiaxed grains with minimal residual stress. It achieves a coercivity of 30 A/m and electrical resistivity of 146 μΩ cm.
The details
The fabrication process relies on non-melting binder jetting combined with high-temperature sintering to produce the material. This approach effectively reduces core loss across the 50-600 Hz frequency range, optimizing it for efficient power electronics.
