High-Saturation Iron-Cobalt-Vacuum Soft Magnetic Alloy Rod
- Ultra-high saturation magnetic induction (2.4T): Enables compact motor/electromagnet designs.
- High Curie point (980℃): Maintains magnetic stability at elevated temperatures.
- High magnetostriction coefficient (60-100×10⁻⁶): Ideal for energy-efficient transducers.
- Limitations: Low resistivity (0.27μΩ·m) restricts high-frequency use; requires oxidation-resistant coatings.
