As a specialized manufacturer of precision-engineered materials, Shanxi Jurun Technology leverages Taiyuan's industrial ecosystem to produce premium DT4 Pure Iron Forged Round Bars with exceptionally low hysteresis loss. Our vertically controlled manufacturing process ensures consistent magnetic properties critical for high-efficiency electromagnetic applications.
These forged bars deliver superior magnetic flux density while minimizing energy dissipation as heat, making them ideal for:
- High-precision relay cores
- Power transformer laminations
- Sensitive instrument components
- Motor armatures requiring minimal eddy current losses
Technical Specifications:
| Property | Value |
|---|---|
| Iron Purity | ≥ 99.8% |
| Saturation Induction | 2.15 T |
| Coercive Force | ≤ 32 A/m |
| Resistivity | 0.1 μΩ·m |
Key Manufacturing Advantages:
- Forging process eliminates internal voids for uniform permeability
- Controlled cooling prevents grain boundary impurities
- Dimensional tolerance: ±0.1mm (for diameters ≤100mm)
- Batch traceability via heat number documentation
Shanxi Jurun's strategic location in China's metallurgical hub enables rigorous material selection and process control. Our DT4 bars undergo triple-stage inspection:
- Spectroscopic composition verification
- Metallographic structure analysis
- Magnetic property testing using Brockhaus measurements
FAQ:
Q: How does DT4 differ from common electrical steels?
A: DT4 features higher saturation flux density (2.15T vs 1.8T in common silicon steels) and lower coercivity, enabling more compact electromagnetic designs.
Q: Can these bars be machined into complex shapes?
A: Yes, our material maintains consistent magnetic properties after CNC machining, though annealing may be required post-machining.
Q: What packaging prevents corrosion during shipping?
A: We use VCI anti-corrosion paper + wooden crates for international shipments, with optional vacuum sealing.
Q: Do you provide material certification?
A: Full traceability documentation including GB/T 6983 compliance reports are standard.
Q: What is the lead time for custom diameters?
A: 25-35 days for non-standard sizes (subject to diameter and quantity).
Q: Can you supply pre-annealed material?
A: Yes, hydrogen-annealed options are available to achieve ≤1.2 W/kg hysteresis loss.
