Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, China, specializes in manufacturing premium electrical pure iron hot-rolled coils engineered specifically for high-performance transformer core applications. Our coils deliver exceptional magnetic properties essential for energy-efficient power transmission systems. With stringent quality control throughout production, we ensure material consistency that meets the demanding requirements of transformer manufacturers worldwide.
Engineered for optimal magnetic flux conduction, our pure iron coils minimize hysteresis and eddy current losses in transformer cores. This translates directly into improved energy efficiency and reduced operational costs for end-users. The material's high saturation induction allows for compact core designs without compromising performance.
Key technical specifications include:
- Core Loss Performance: Significantly lower than standard commercial irons at various frequencies
- Permeability: High initial and maximum permeability values
- Surface Quality: Uniform oxide-free surface after pickling
- Dimensional Tolerance: Tight thickness control within ±0.03mm
| Property | Value | Test Method |
|---|---|---|
| Resistivity | 12 μΩ·cm | ASTM B193 |
| Density | 7.85 g/cm³ | ASTM B328 |
| Coating | Bare / Insulation Optional | N/A |
For transformer manufacturers, our material enables:
- Reduced no-load losses by 15-25% compared to conventional cores
- Lower operating temperatures extending transformer lifespan
- Improved voltage regulation through superior magnetic response
- Noise reduction in power distribution transformers
Leveraging our strategic location in Shanxi Province, a region with abundant metallurgical resources, we maintain consistent material quality through vertically integrated production. Our manufacturing facilities employ continuous annealing lines that ensure uniform magnetic properties across the entire coil length. Rigorous testing protocols include Epstein frame measurements and visual inspection systems that guarantee dimensional accuracy and surface integrity.
As an established supplier to the electrical steel market, Shanxi Jurun Technology has developed specialized logistics solutions for coil transportation, including corrosion-inhibiting packaging and secure crating for overseas shipments. We offer flexible order quantities from trial batches to full container loads, supported by technical consultation for optimal material selection in your transformer designs.

Frequently Asked Questions:
Q: What purity level does your electrical pure iron maintain?
A: Our coils maintain iron content exceeding 99.8%, with controlled trace elements to optimize magnetic properties.
Q: Can you provide custom widths beyond the standard range?
A: Yes, our rolling mills can accommodate custom widths from 600mm to 2000mm with advance notice.
Q: Do you offer insulation coating services?
A: Insulation coatings (C-5 and C-6 grades) are available as an optional processing step.
Q: What packaging methods do you use for overseas shipment?
A: Coils are protected with VCI paper and moisture barrier wrapping, then secured in wooden crates for ocean transport.
Q: How do you ensure magnetic property consistency?
A: We implement statistical process control throughout annealing and employ Epstein testing on every production batch.
Q: What is your typical lead time for 20MT orders?
A: Standard lead time is 30-45 days ex-works, with expedited production available.
