Industrial Pure Iron Cold Rolled Sheet DT4C With High Saturation Magnetic Flux Density for Motor CoresNegotiableMOQ: 1 Ton
Engineered for exceptional magnetic performance, our High Purity Cold Rolled Electrical Pure Iron Sheet delivers unparalleled efficiency in energy conversion applications. With iron purity exceeding 99.8%, this specialized material significantly reduces core losses in transformers and motors while enhancing magnetic flux density. The precision cold rolling process ensures uniform thickness and superior surface quality for seamless manufacturing integration.
Manufacturers seeking to optimize electromagnetic device performance will appreciate the consistent material properties and customizable dimensions tailored to specific application requirements. Unlike standard electrical steels, this pure iron variant maintains stable permeability across varying operational temperatures, making it particularly suitable for high-reliability industrial equipment.
- ▲ Reduced Hysteresis Loss: Minimizes energy waste through optimized crystalline structure
- ▲ Enhanced Saturation Flux Density: 1.5-1.8T rating improves power density
- ▲ Low Coercivity (< 80 A/m): Requires less magnetizing force for efficient operation
- ▲ Annealed Surface: Oxide-free finish prevents interlamination shorts
| Parameter | Value Range | Testing Standard |
| Thickness Tolerance | ±0.02mm - ±0.05mm | ASTM A480 |
| Surface Roughness (Ra) | ≤ 0.8 μm | ISO 4287 |
| Resistivity | ≥ 0.12 μΩ·m | IEC 60404-8 |
The material's isotropic magnetic properties ensure consistent performance regardless of lamination orientation during stamping operations. For high-frequency applications, thinner gauges (0.35mm - 0.65mm) effectively suppress eddy currents while maintaining structural rigidity. Custom annealing treatments can be applied to achieve specific hardness requirements (70-85 HRB).
- 20-30% lower core loss at 1.0T/50Hz excitation
- 15% higher permeability in medium flux density ranges
- Superior DC bias characteristics for choke applications
Our production facility utilizes vacuum degassing and controlled rolling technology to eliminate impurities that compromise magnetic performance. Each batch undergoes rigorous quality verification including Epstein testing and surface inspection. Additional processing services such as slitting, annealing, and insulation coating are available upon request.
