Cold Rolled Electromagnetic Pure Iron Thin Sheet for Magnetic Cores Manufacturing
Shanxi Juli Run Technology presents premium Cold Rolled Electromagnetic Pure Iron Thin Sheet engineered specifically for high-performance magnetic cores manufacturing. Our pure iron sheets deliver exceptional magnetic properties with minimal core loss, making them ideal for demanding applications in transformers, relays, and precision instruments.
Manufactured through advanced cold rolling processes in Taiyuan, China, these sheets feature:
- Superior magnetic permeability ensuring efficient energy transfer
- Ultra-low hysteresis loss for reduced heat generation
- Consistent thickness tolerance (±0.01mm) for precision stacking
- Customizable dimensions to fit specialized core designs
Technical specifications include:
| Property | Value |
|---|---|
| Thickness Range | 0.1mm - 3.0mm |
| Maximum Width | 1000mm |
| Coercive Force (Hc) | ≤ 80 A/m |
| Resistivity | ≥ 0.10 μΩ·m |
| Surface Roughness (Ra) | ≤ 0.8 μm |
Key benefits for manufacturers:
- Reduced core assembly time due to precise dimensional control
- Up to 18% improvement in magnetic flux density compared to standard electrical steel
- Excellent punchability with minimal burr formation during stamping
- Compatibility with various insulation coating processes
Applications include power transformers, current sensors, electromagnetic shielding, and precision motors where consistent magnetic performance is critical. Our production facility maintains strict process controls to ensure batch-to-batch consistency and traceability.

Frequently Asked Questions:
Q: What is the maximum coil weight available?
A: Standard coils weigh up to 5 tons, but larger sizes are available upon request.
Q: Do you provide material certification?
A: Yes, we supply mill test reports with chemical composition and magnetic properties data.
Q: Can I get samples before bulk ordering?
A: Sample sheets (A4 size) can be provided for material evaluation.
Q: How does this compare to silicon steel?
A: Our pure iron offers higher saturation flux density (up to 2.15T) but requires proper insulation coating.
Q: What lead time should I expect?
A: Standard thicknesses ship in 2-3 weeks; custom orders require 4-5 weeks.
Q: Is edge trimming available?
A: Yes, we can provide slit edges with controlled burr ≤0.02mm.
