Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, China, specializes in manufacturing premium annealed pure iron sheets engineered for critical electromagnetic applications. Our cold rolled sheets comply with ASTM A848 standards, delivering exceptional magnetic performance essential for energy-efficient components. With meticulously controlled purity levels and specialized annealing processes, we provide material solutions that significantly enhance device efficiency while reducing operational costs.
Core Technical Advantages:
- Ultra-low carbon content (≤0.008%) ensuring minimal magnetic hysteresis
- Precision cold rolling achieving surface roughness Ra ≤ 0.8μm
- Controlled annealing atmosphere preventing surface oxidation
- Consistent thickness tolerance of ±0.02mm across production batches
- Homogeneous grain structure (ASTM 6-8) for uniform magnetic response
Performance Specifications:
| Property | Value |
|---|---|
| Maximum Permeability | ≥ 6000 μH/m |
| Coercive Force (Hc) | ≤ 80 A/m |
| Core Loss (1.5T/50Hz) | ≤ 4.5 W/kg |
| Electrical Resistivity | ≥ 0.12 μΩ·m |
These specifications translate to tangible benefits for electromagnetic component manufacturers. When used in transformer cores, relay components or sensor assemblies, our material delivers:
- 15-20% reduction in eddy current losses compared to standard electrical steel
- Improved Q-factor in inductive components
- Enhanced signal-to-noise ratio in sensitive measurement devices
- Extended service life through reduced thermal stress
Frequently Asked Questions:
Q: What thickness options are available?
A: Standard thickness ranges from 0.5mm to 3.0mm, with custom gauges available upon request.
Q: How does annealing improve performance?
A: Our controlled annealing process relieves internal stresses from cold rolling, optimizing magnetic domain alignment and permeability.
Q: Can I get material certification?
A: Full material test reports including chemical composition and magnetic properties accompany each shipment.
Q: What protective packaging is used?
A: Sheets are interleaved with anti-corrosion paper and packed in moisture-proof wooden crates for international shipping.
Q: Are custom dimensions available?
A: Yes, we can produce sheets to your specified width (max 1500mm) and length requirements.
Q: What's the lead time for orders?
A: Standard specifications ship within 15 working days; custom orders typically require 25 working days.
Leveraging Shanxi Jurun's strategic location in China's metallurgical center, we maintain rigorous quality control through every production stage - from raw material selection to final annealing. Our Taiyuan facility operates with dedicated electromagnetic material production lines, ensuring batch-to-batch consistency that major component manufacturers require.
