Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, China, specializes in manufacturing precision-engineered DT4C Cold Rolled Pure Iron Sheets for demanding electromagnetic applications. Our cold-rolled plates deliver exceptional magnetic performance in high-frequency environments, making them ideal for critical components where efficiency and reliability are paramount.
Key technical advantages include:
- Superior DC Bias Performance: Maintains stable permeability under varying magnetic fields
- Ultra-Low Core Loss: Reduces energy dissipation by up to 40% compared to conventional silicon steel
- High Saturation Flux Density: 2.15T minimum at 50Hz operation
- Controlled Thickness Tolerance: ±0.02mm precision for consistent lamination stacking
Typical specifications for high-frequency applications:
| Parameter | Value Range | Test Condition |
| Thickness | 0.1mm - 0.5mm | ASTM A34 |
| Coercivity (Hc) | ≤ 80 A/m | 1.5T, 50Hz |
| Resistivity | 0.45 μΩ·m | 20°C |
This material demonstrates particular benefits in:
- High-frequency power transformers (10kHz - 100kHz)
- Pulse compression inductors for medical imaging equipment
- Aerospace-grade electromagnetic actuators
- Precision sensors requiring minimal magnetic hysteresis
Backed by Shanxi Jurun's metallurgical expertise, all DT4C sheets undergo rigorous quality control including:
- Continuous annealing under hydrogen atmosphere
- Laser-based thickness mapping across entire coil
- Epstein frame testing for magnetic consistency
With over 15 years of specialized production in Taiyuan, our manufacturing facility maintains ±2% dimensional consistency across batches. Custom widths up to 1200mm and protective VCI packaging are available to meet specific project requirements. Contact our engineering team today for technical data sheets and sample requests.
FAQ:
Q1: What distinguishes DT4C from standard electrical steel?
A: DT4C offers higher purity (99.8% Fe) with controlled carbon content below 0.004%, significantly reducing eddy current losses at frequencies above 10kHz.
Q2: Can I get custom annealing treatments?
A: Yes, we provide optional decarburization annealing to achieve core losses as low as 12W/kg at 1.5T/400Hz.
Q3: What packaging options prevent corrosion during shipping?
A: All materials are coated with antioxidant oil and shipped in vacuum-sealed packs with desiccant, or VCI paper for long-term storage.
Q4: Do you supply pre-cut laminations?
A: Custom stamping and laser cutting services are available upon request with minimum order quantities.
Q5: What is the lead time for 0.2mm thickness?
A: Standard gauge stock ships within 7 working days; custom annealing adds 3-5 days.
Q6: How does temperature affect performance?
A: Permeability remains stable between -40°C to 150°C, with Curie temperature at 770°C.
