Engineered for precision electromagnetic applications, our DT4 Pure Iron Seamless Tube delivers exceptional magnetic performance with minimal energy loss. Manufactured through specialized cold-drawing processes, these tubes maintain material integrity while achieving dimensional accuracy within ±0.1mm tolerances. The 99.8% pure iron composition ensures consistent magnetic flux density across industrial operating temperatures ranging from -20°C to 150°C.
Key technical advantages include:
- Ultra-Low Core Loss: Hysteresis loss below 2.5W/kg at 1.5T/50Hz
- High Permeability: Initial μ ≥ 5000 (tested at 0.002T)
- Controlled Impurities: Carbon content ≤ 0.015% by weight
- Surface Quality: Ra ≤ 0.8μm roughness for reduced eddy currents
Standard specifications include:
| Parameter | Value | Testing Standard |
|---|---|---|
| Outer Diameter | 6-120mm (±0.05mm) | GB/T 3639 |
| Wall Thickness | 0.5-10mm (±5%) | ASTM A450 |
| Saturation Induction | ≥2.15T | IEC 60404-8 |
| Coercivity | ≤72A/m | JIS C 2531 |
These electromagnetic tubes significantly enhance system efficiency in critical applications including:
- MRI scanner components
- Precision current sensors
- Aerospace navigation systems
- High-frequency transformers
Shanxi Juli Run Technology provides comprehensive technical support for custom requirements, with production lead times starting at 30 days for standard specifications. All products undergo triple-stage quality verification including ultrasonic testing, dimensional inspection, and magnetic property analysis.
FAQ Section
Q1: What distinguishes DT4 from other electromagnetic pure iron grades?
A: DT4 features stricter control of non-metallic inclusions and lower carbon content (≤0.015%) compared to commercial pure iron, resulting in approximately 15% lower hysteresis loss.
Q2: Can these tubes be welded without degrading magnetic properties?
A: Specialized TIG welding with argon shielding is recommended to prevent contamination. Post-weld annealing at 850°C restores magnetic characteristics.
Q3: What packaging options protect against corrosion during shipping?
A: We offer VCI anti-rust paper wrapping + vacuum sealing for standard orders, with nitrogen-filled crates available for critical applications.
Q4: Do you provide material certification documentation?
A> Full traceability reports including chemical composition analysis and magnetic test certificates accompany each shipment.
Q5: What minimum order quantities apply?
A: MOQ starts at 50kg for standard sizes, with prototype batches available for R&D projects.
