Why Hiperco 50A (FeCo50A) Alloy Powder Is Ideal for High-Performance Magnetic Applications

Published by HUAXIAO TECH manufacturer

As industries push for higher energy efficiency and miniaturization, soft magnetic materials are becoming essential. Hiperco 50A (FeCo50A) alloy powder stands out due to its unmatched magnetic saturation and low core loss, making it the material of choice for aerospace, electric motors, and advanced magnetic components.

Outstanding Magnetic Properties

Hiperco 50A is composed of approximately 49% cobalt and 49% iron, engineered for superior magnetic performance. Its key characteristics include:

• Extremely high magnetic saturation (up to 2.4 Tesla)

• Low coercivity, enhancing permeability

• Excellent performance in both static and dynamic magnetic fields

These features ensure efficient energy conversion and reduced heat generation, critical for high-frequency and high-power applications.

High Temperature Stability

Compared with standard silicon steels, Hiperco 50A maintains magnetic stability under extreme conditions:

• Operates reliably at temperatures exceeding 450°C

• Excellent thermal conductivity, reducing localized heating

• Suitable for use in high-speed rotating machines and aerospace actuators

Frequently Asked Questions (FAQ)

Q1: What is the typical particle size range for AM?
A1: Standard AM-grade powder ranges from 15–53 μm. Finer grades (5–25 μm) are available for MIM or binder jetting.

Q2: Does Hiperco 50A require post-processing for magnetic performance?
A2: Yes. Optimal magnetic properties are achieved after appropriate heat treatment (e.g., 1150°C annealing in hydrogen).

Q3: How is oxidation controlled during production?
A3: The powder is produced under inert gas atomization and stored under vacuum-sealed or nitrogen-protected packaging.

Conclusion

Hiperco 50A (FeCo50A) alloy powder delivers industry-leading magnetic performance and thermal stability. Its compatibility with additive manufacturing makes it an optimal solution for next-generation high-speed, high-efficiency electrical devices.
