Shanxi Jurun Technology Co., Ltd., a trusted manufacturer based in Taiyuan, China, specializes in producing premium Electrical Pure Iron Cold Rolled Coils. Our 0.35mm thickness coils deliver exceptional magnetic performance for critical electromagnetic applications, ensuring reliability in demanding industrial environments. With rigorous quality control from our Shanxi facility, we provide material solutions that meet precise technical specifications while optimizing energy efficiency in end products.
Core Features & Technical Advantages:
- Superior Magnetic Properties: Exhibits high magnetic permeability (up to 12,000 μ) and low coercive force (≤80 A/m), reducing energy loss in electromagnetic devices.
- Precision Thickness Control: Maintains consistent 0.35mm ±0.02mm tolerance across coils for uniform performance in layered components.
- Low Impurity Content: Carbon ≤ 0.003%, Sulfur ≤ 0.003%, and Phosphorus ≤ 0.015% ensure minimal eddy current losses.
- Customizable Dimensions: Available in widths ranging from 800mm to 1200mm with coil weights up to 8 metric tons.
Technical Specifications:
| Parameter | Value | Test Standard |
|---|---|---|
| Yield Strength | ≥ 180 MPa | ASTM E8 |
| Coercive Force | ≤ 80 A/m | IEC 60404-4 |
| Surface Roughness (Ra) | ≤ 0.8 μm | ISO 4287 |
| Density | 7.85 g/cm³ | ASTM B311 |
