Wichtige Eigenschaften:

(1)、Exzellente elektromagnetische Eigenschaften: Niederige Koerzitivfeldstärke (Hc), hohe Permeabilität (μ), hohe Sättigungsflussdichte (Bs), stabile Magnetismus und kein magnetisches Altern.

(2)、Hohe Reinheit: Die Serie des elektromagnetischen Reineisens besteht aus vollentspannten Stählen und wird durch Raffinationsprozesse hergestellt, was zu einer dichten, gleichmäßigen und überlegenen inneren Struktur mit niedrigem Gasgehalt führt. Der typische Kohlenstoffgehalt im Fertigprodukt ist<0.004%, which provides reliable conditions for users to simplify and shorten the part annealing process.

(3)、Good Cold and Hot Workability:

Cold working such as turning, upsetting, punching, bending, and drawing can be performed without issues.

Hot working, such as re-forging or re-rolling, shows low sensitivity to red shortness. Many grades have no red-shortness range, allowing processing within a wide temperature window.

(4)、Good Surface Quality: Exhibits excellent weldability and plating performance.

(5)、High Dimensional Accuracy: Can supply ultra-precision cold-rolled sheets. For sheet thickness ≤1.5mm, the thickness tolerance can be guaranteed within ≤±0.03mm; for thickness >1.5mm, the tolerance is within ≤±0.05mm.

Applications:

Electromagnetic pure iron is primarily used in the electrical, telecommunications, instrumentation, and advanced defense industries to manufacture electromagnetic components and iron cores.

1.  Relay Cores, Armatures, and Yokes in electrical and telecommunications systems: For relays in automatic telephones, railway signal relays, and various purpose relays (e.g., thermal, pulse, time-delay, special type) used in communication and automatic control systems, as well as relays for electrical control equipment.

2.  Core Material for Electromagnets: Iron cores for bending and focusing magnets in high-energy accelerators, acoustic devices, solenoid valves, and electromagnets for magnetic separation equipment.

3.  Soft Magnetic Components for Instruments and Meters: High-resolution pole pieces for analytical instruments, electromagnetic separators and detectors in geological instruments, focusing magnets for electron microscopes and electromagnetic lenses for scanning electron microscopes, aircraft automatic control components, and pole pieces for magnetizers.

4.  Cores and Housings for DC Motors: Such as those used in aviation DC motors.

5.  Electrical and Magnetic Parts for Automobiles, Tractors, and Machine Tools: Including automotive voltage regulators, flashers, starters, horns, electromagnetic chucks for machine tools, magnetic plates, and other magnetic conduits.

6.  Magnetic Shielding Equipment: Various magnetic shielding casings or boxes, and shielding materials for applications requiring high shielding effectiveness.

Ordering Instructions:

(1) Select the correct grade: Grades DT3 and DT3A do not guarantee freedom from magnetic aging. For guaranteed non-aging properties, order DT4 (A, E, C). Magnetic performance levels are Standard, Advanced (A), Extra High (E), and Super (C). For higher magnetic performance, specify higher grades (E, C).

(2) Guaranteed properties: The electromagnetic pure iron series generally guarantees electromagnetic performance; chemical composition is not the acceptance criterion unless specified by the customer in the contract.

(3) Magnetic annealing: The electromagnetic properties of our products are measured on test samples after magnetic annealing. However, products are delivered in hot-rolled, hot-forged, or softened annealed (for cold-rolled/cold-drawn material) conditions. Therefore, to fully realize the material's magnetic potential, parts must undergo magnetic annealing after manufacturing.

* Simplified Annealing Process (if carbon content ≤ 0.007%): 850°C for 3 hours.

* Standard Annealing Process (if carbon content > 0.007%): Follow the process specified by the Chinese National Standard (GB).

(4) Standard magnetic tests: Typically, only coercivity (Hc) and post-aging coercivity are routinely tested. If guarantees for magnetic induction (B) or maximum permeability (μm) are required, please specify this in the contract.

(5) High-precision cold-rolled material: For extra-thickness precision in cold-rolled materials, please order Super Precision Cold-Rolled Sheet according to standard YB(T) 34-86.

(6) Custom specifications: For requirements exceeding current GB or YB(T) standards, we can negotiate and establish a separate technical agreement for supply.

(7) Delivery time: For standard, non-processed goods, the delivery period is typically 1-2 working days. For goods requiring additional processing, the delivery time will be determined based on the complexity of the drawings.
