Key Material Features
- Low coercivity: Easy magnetization and demagnetization, stable performance under variable magnetic‑field conditions.
- Excellent machinability: Readily formed and stamped into intricate, complex component geometries for flexible design solutions.
- Superior thermal stability: Retains consistent magnetic properties at elevated temperatures, delivering reliable operation under demanding service environments.
- High saturation magnetic induction (1.56 T): Higher flux‑carrying capacity compared with high‑nickel permalloy grades for medium‑magnetic‑field working scenarios.
