Shanxi Juli Run Technology Co., Ltd. presents Electromagnetic Pure Iron Hot-Rolled Coil DT4C – engineered for superior magnetic performance in demanding electrical applications. This high-permeability material delivers exceptional magnetic flux density with minimal core losses, making it ideal for energy-efficient motors and transformers operating under variable frequencies. Manufactured through precision-controlled hot-rolling and annealing processes, our coils ensure consistent electromagnetic properties across entire batches.
Key advantages include:
Reduced hysteresis losses by up to 30% compared to conventional electrical steels
Excellent saturation induction (up to 2.15T) for compact component design
Low coercivity (
Customizable dimensions to fit specific winding and stamping requirements
Technical specifications for standard grades:
| Parameter | Value | Testing Standard |
|---|---|---|
| Core Loss (W/kg @1.5T/50Hz) | ≤4.5 | GB/T 3655 |
| Permeability (μmax) | ≥15,000 | GB/T 3656 |
| Resistivity (μΩ·m) | 0.10-0.13 | GB/T 351 |
| Coil Weight | 3-10 MT (standard) | N/A |
Our DT4C coils undergo strict quality control including:
Eddy current testing for thickness uniformity
Epstein frame validation of magnetic properties
Surface inspection for defects exceeding 0.1mm depth
Applications extend beyond standard transformers and motors to include:
High-frequency inductors for power electronics
Magnetic shielding in sensitive equipment
Relay cores requiring fast magnetization
Solenoid valves and actuators
For OEMs and electrical component manufacturers, our material enables:
15-20% weight reduction in rotating machinery
Compliance with IE4/IE5 efficiency standards
Lower operating temperatures extending device lifespan
FAQ:
Q: What surface treatment options are available?
A: Standard coils are supplied with annealed oxide surface. Epoxy coating or phosphating can be arranged upon request.
Q: Can I get customized slit widths?
A: Yes, we offer precision slitting services from 20mm to 600mm widths with ±0.1mm tolerance.
Q: How does DT4C compare to M19 silicon steel?
A: DT4C offers approximately 18% lower core losses at 50Hz and higher saturation flux density, making it preferable for high-torque applications.
Q: What is the lead time for 10MT orders?
A: Standard specifications ship within 15 days; custom-processed orders require 25-30 days production time.
Q: Do you provide material certification?
A> Full mill test certificates including chemical composition and magnetic properties accompany every shipment.
