### Application Scope of 1J22

**Application Areas:**  

The 1J22 alloy is utilized in various applications, including:

- Electromagnet pole heads  

- End-welded tubes in magnetrons  

- Vibration membranes for telephone headsets  

- Torque motor rotors  

- Magnetostrictive transducer cores  

**Uses:**  

1J22 exhibits high saturation magnetic induction intensity, making it suitable for manufacturing compact and lightweight components in aerospace and instrumentation. Among existing soft magnetic materials, this alloy possesses the highest saturation magnetic induction intensity (2.4 T), a high Curie point (980 °C), and the largest saturation magnetostriction coefficient (60 ~ 100 × 10⁻⁶). 

Due to its high saturation magnetic induction intensity, the volume of motors can be significantly reduced while maintaining the same power output. Additionally, when utilized as electromagnets, it can generate substantial attraction forces within the same cross-sectional area. The high Curie point enables the alloy to operate at elevated temperatures where other soft magnetic materials may become demagnetized, ensuring excellent magnetic stability under such conditions.
