Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, China, specializes in manufacturing premium electromagnetic pure iron coils engineered for critical applications in motor and generator production. Our DT4 series delivers exceptional magnetic properties essential for energy-efficient electromagnetic components.
Manufactured with precision-controlled processes, these coils offer superior magnetic permeability and minimal core losses, translating to enhanced performance in rotating machinery. As a trusted supplier to OEMs worldwide, we ensure consistent material characteristics through rigorous quality protocols at every production stage.
The DT4 electromagnetic pure iron coil represents an optimal solution for applications demanding high saturation flux density combined with excellent machinability. Its unique properties significantly reduce eddy current losses while maintaining structural integrity under varying operational stresses.
Key technical advantages include:
- Controlled purity levels (99.8%+ iron content) ensuring predictable magnetic behavior
- Homogeneous crystalline structure for uniform magnetic flux distribution
- Precision-rolled surfaces with controlled tolerances (±0.02mm)
- Tailored annealing treatments optimizing magnetic domain alignment
Critical performance parameters include:
| Property | Value | Test Condition |
|---|---|---|
| Saturation Flux Density | 2.15 T | H = 5000 A/m |
| Core Loss (W/kg) | ≤ 4.5 | 1.5T @ 50Hz |
| Relative Permeability | ≥ 5000 | B = 1.0T |
| Resistivity | 0.12 μΩ·m | 20°C |

Frequently Asked Questions:
Q: What distinguishes DT4 pure iron from standard electrical steel?
A: DT4 offers higher saturation flux density (2.15T vs 1.6-2.0T in silicon steel) and superior permeability, making it ideal for compact, high-performance electromagnetic devices.
Q: Can these coils be supplied with protective coatings?
A: Various surface treatments including phosphating, nickel plating, and organic coatings are available to prevent corrosion during storage and processing.
Q: What tolerances can be maintained on coil dimensions?
A: Standard tolerances are ±0.05mm on thickness and ±1mm on width, with tighter tolerances achievable for precision applications.
Q: How does this material perform in high-frequency applications?
A: While optimized for 50-400Hz applications, special annealing treatments can extend performance to 1kHz for specific use cases.
Q: What minimum order quantities apply?
A: Standard MOQ is 500kg, with prototype quantities available for new product development.
Q: What packaging options are available?
A: We offer moisture-resistant packaging including VCI paper, steel strapping, and wooden pallets suitable for international shipping.
