As a specialized manufacturer based in Taiyuan, Shanxi, Shanxi Jurun Technology Co., Ltd. produces premium DT4 Pure Iron Tubes engineered for high-precision instrumentation applications. Our tubes deliver exceptional magnetic permeability characteristics essential for sensitive measurement devices, ensuring accurate signal transmission and minimal energy loss. Leveraging regional material expertise, we maintain stringent quality control throughout the manufacturing process to meet critical industrial specifications.
The DT4 grade pure iron tubes feature:
- Ultra-high relative permeability exceeding 15,000 μ/μ0
- Controlled carbon content below 0.025% for minimal magnetic hysteresis
- Homogenous crystalline structure through specialized annealing processes
- Precision dimensional tolerances within ±0.05mm
| Property | Value |
|---|---|
| Electrical Resistivity | 0.12 μΩ·m |
| Saturation Induction | 2.15 Tesla |
| Coercive Force | < 32 A/m |
| Operating Temperature | -40°C to +150°C |
These advanced material properties translate to significant benefits for instrumentation engineers:
- Enhanced signal-to-noise ratio in sensitive measurement applications
- Reduced eddy current losses in high-frequency components
- Improved linearity in magnetic field sensing devices
- Extended service life due to consistent material performance
Manufactured in Shanxi – China's traditional center for advanced metallurgy – our tubes undergo multiple quality verification stages including ultrasonic testing, dimensional verification, and magnetic property analysis. This ensures consistent performance across production batches, providing reliability for critical instrumentation applications in medical, aerospace, and research sectors.
Frequently Asked Questions:
Q: What makes DT4 different from standard pure iron?
A: DT4 grade undergoes specialized purification and annealing processes to achieve magnetic properties significantly superior to commercial pure iron, particularly in permeability and coercivity values.
Q: Can these tubes be machined after delivery?
A: While we recommend final machining prior to magnetic annealing, limited mechanical processing is possible with proper tooling and cooling techniques to preserve magnetic characteristics.
Q: What surface protection options are available?
A: Various anti-corrosion treatments including nickel plating, phosphating, and specialized coating systems can be applied based on application environment requirements.
Q: How do you ensure dimensional accuracy?
A: We utilize CNC-controlled pilgering mills with laser measurement feedback systems, complemented by statistical process control methodologies.
Q: What packaging methods protect these sensitive components?
A: We employ VCI (Vapor Corrosion Inhibitor) packaging with rigid tubular supports to prevent mechanical damage and corrosion during transit.
Q: Can custom magnetic testing be performed?
A: Yes, specialized magnetic characterization including B-H curve mapping under specific field conditions can be arranged upon request.
