Cobalt Vanadium Iron
Soft magnetic material
Magnetic iron-cobalt-vanadium alloy is primarily composed of cobalt and iron. It offers several unique features, including high saturation magnetization (Bs), which reaches up to 2.4T, the highest among soft magnetic alloys. Also, the alloy's high Curie temperature (Tc) and large magnetostriction coefficient (with 1J22 reaching 60～100×10-6) allow for efficient energy output and stability at higher temperatures.
However, the low resistivity and high eddy current losses make it unsuitable for high-frequency applications. Adding elements like Ni or V can enhance the alloy's processability and oxidation resistance.
NGYC's Cobalt Vanadium Iron is widely used in various applications such as aviation electronics, micro motors, electromagnetic coils, relays, and motors, where miniaturization and high-temperature resistance are critical.

- Our 1J22 series alloys, including 1J21, 1J22, and 1J22HK, exhibit excellent magnetic properties such as high saturation magnetic induction, high Curie temperature, and high magnetostriction coefficient, while maintaining excellent mechanical strength.
- Additionally, though showing slightly lower magnetic performance, 1J27 offers better ductility, fatigue resistance, processability, and weldability.
