Shanxi Jurun Technology, based in Taiyuan, China, specializes in producing premium Electrical Pure Iron Cold Rolled Sheets engineered for high-performance transformer cores. Our cold-rolled pure iron delivers exceptional magnetic properties critical for energy-efficient power conversion systems. With precise thickness control from 0.5mm to 3mm, these sheets enable manufacturers to optimize transformer designs for reduced core losses and enhanced operational efficiency.
Key technical advantages include:
- Ultra-low carbon content (
- Controlled grain orientation for superior flux density (up to 1.8T)
- Consistent surface quality with Ra ≤ 0.8μm for uniform interlaminar insulation
- Customizable annealing processes to achieve target hardness (45-80 HRB)
| Thickness (mm) | Tolerance (mm) | Typical Core Loss (W/kg @ 1.5T/50Hz) | Permeability (μmax) |
|---|---|---|---|
| 0.5 | ±0.03 | 1.8 | 5,500 |
| 1.0 | ±0.05 | 2.1 | 6,200 |
| 2.0 | ±0.07 | 2.5 | 7,000 |
Manufacturing benefits for transformer producers:
- Reduced no-load losses by 12-18% compared to conventional steels
- Improved stacking factor (≥96%) through thickness uniformity
- Compatible with laser cutting and chemical etching processes
- Available with C5/C6 insulation coatings upon request
FAQ Section:
-
Q: What is the minimum order quantity?
A: Standard MOQ is 5 metric tons, with sample rolls available for testing. -
Q: Can you provide custom widths?
A: Yes, we can produce sheets from 200mm to 1000mm width based on coil slitting requirements. -
Q: How does pure iron compare to silicon steel?
A: Pure iron offers higher saturation flux density (2.15T vs 1.9T) but requires careful lamination design to manage eddy currents. -
Q: What packaging options are available?
A: Standard export packaging includes PVC-coated steel strapping on wooden pallets with moisture-resistant wrapping. -
Q: Can you supply pre-treated surfaces for bonding?
A: Phosphatization and chromate conversion treatments are available for improved interlaminar resistance. -
Q: What is the lead time for 20-ton orders?
A: Standard production lead time is 25-30 days ex-works.
