Performance Advantages
1. Magnetic Performance That Stays Consistent
Pure iron is known for its strong response to magnetic fields. Our bars maintain very low hysteresis loss, making them perfect for:
Transformers
Magnetic shields
Electromagnets
Magnetic switches
2. Superb Workability
Electrical pure iron has a softer nature compared to low-alloy steels, allowing:
Deep machining
Bending
Punching
Cold forming without cracking
3. Stable Under High-frequency Conditions
When exposed to repeated cycles, our material maintains both microscopic stability and dimensional integrity.
Applications
Motor components
Relay cores
Electric vehicle sensors
Solenoid valve plungers
Inductive charging systems
High-end magnetic instruments
