Electrical Pure Iron Cold Rolled Sheet DT4C Grade for Industrial Applications

Shanxi Juli Run Technology presents premium cold-rolled electrical pure iron sheets engineered for demanding industrial applications. Our DC01/DC04/DT4 grade material delivers exceptional magnetic performance essential for electromagnetic components across multiple sectors.

Manufactured with precision rolling technology in Taiyuan, China, these sheets feature:

• Consistent thickness tolerance within ±0.02mm

• Superior surface quality with Ra ≤ 0.8μm

• Controlled crystal orientation for optimized flux density

• Annealed finish for enhanced formability

The material's electromagnetic characteristics make it particularly suitable for:

Key technical advantages include:

• Reduced core loss - Up to 15% lower than commercial grades at 1.5T/50Hz

• Improved stacking factor - Enables compact component design

• Excellent punching characteristics - Minimizes tool wear during stamping

• Batch consistency - Controlled chemical composition (C≤0.008%, Si≤0.03%)

Our cold-rolled sheets undergo rigorous quality control including:

1. Ultrasonic thickness mapping across full coil width

2. Eddy current testing for surface defects

3. Epstein frame verification of magnetic properties

4. Statistical process control of mechanical parameters

Applications span from small relay cores to large transformer laminations, serving industries including:

• Power equipment manufacturing

• Electric vehicle motor production

• Precision sensor fabrication

• Industrial automation systems

Customization options include:

• Slitting to widths from 10mm to 1250mm

• Special protective coatings (phosphating available)

• Precision leveling for flatness ≤1.5mm/m

• Vacuum annealing for critical applications

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.
