FeCoNi soft magnetic alloy powder
High frequency, low loss · High permeability · Specifically for electromagnetic shielding -80+150 mesh / -150+250 mesh

FeCoNi soft magnetic alloy powder, composed of iron (Fe), cobalt (Co), and nickel (Ni), exhibits excellent properties including high saturation magnetic induction, high permeability, low coercivity, and high resistivity. It is well suited for MHz‑range high‑frequency applications, offers a wide operating temperature range, and maintains stable magnetic performance. Prepared by non‑vacuum gas atomization, it features good sphericity and excellent flowability, with an oxygen content of ≤0.20%, making it compatible with processes such as die pressing, metal injection molding (MIM), and additive manufacturing. The core technical team hails from the Powder Metallurgy Research Institute of Central South University.

Process Advantages

High frequency, low loss

High resistivity effectively suppresses eddy‑current losses, while low coercivity reduces hysteresis losses, resulting in excellent energy efficiency under high‑frequency operating conditions.

High magnetic permeability

High initial permeability, optimized magnetic circuit design, and enhanced energy conversion efficiency and device sensitivity.

Wide-temperature stability

The magnetic properties exhibit minimal variation across a wide temperature range and maintain excellent stability even at elevated temperatures.

High sphericity

Prepared by a non‑vacuum gas atomization process, the powder exhibits excellent sphericity, minimal satellite particles, and superior flowability, making it well suited for both powder compaction and additive manufacturing.

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.
