On FeCoNi Soft Magnetic Alloy Powders
FeCoNi ternary soft magnetic alloy is an important branch within the field of soft magnetic materials. Compared with conventional pure‑iron soft magnetic materials and iron–silicon–aluminum magnetic powder cores, FeCoNi alloys achieve a favorable balance among high saturation magnetic flux density, high permeability, and high resistivity through the synergistic effects of iron, cobalt, and nickel. In high‑frequency applications, they exhibit lower eddy‑current losses and hysteresis losses. This system combines the excellent formability of the face‑centered cubic (FCC) phase with the high saturation magnetization of the body‑centered cubic (BCC) phase, making it a soft magnetic material with outstanding overall performance. By employing a non‑vacuum gas atomization powder‑making process, the resulting powders exhibit good sphericity and tightly controlled oxygen content, enabling compatibility with a variety of forming techniques—including insulating coating, compression molding, metal injection molding (MIM), and additive manufacturing—thus meeting the diverse requirements of high‑frequency inductors, transformer cores, electromagnetic shielding, sensors, and other applications spanning from kHz to MHz frequencies.
