Professional terms and practical application case analysis
Amorphous soft magnetic alloy wire refers to an amorphous alloy material prepared by a rapid solidification process, which has excellent soft magnetic properties. It is particularly widely used in power electronics and medical equipment.
Comparison of standard framework and analysis of technological evolution
Compared with the old version of the standard, GB/T 44654-2024 has achieved important breakthroughs in the following aspects:
- Introduced more accurate magnetic property test methods (Appendix B, C, D)
- Expanded the scope of application, and included the diameter range from 0.02 mm to 0.16 mm in the standard management
- Added reference to typical values of chemical composition and physical parameters (see Table A.1 and Table A.2)
Implementation recommendations and precautions
To ensure that the quality of amorphous soft magnetic alloy wire meets the requirements of GB/T 44654-2024, it is recommended to take the following measures:
- Raw material control: Strictly control the chemical composition of the master alloy, especially the ratio of cobalt (Co), iron (Fe) and boron (B).
- Process optimization: Improve the rapid quenching process parameters to ensure the uniformity of amorphous structure.
- Equipment calibration: Regularly calibrate the magnetic performance testing equipment to ensure measurement accuracy.
