Shanxi Juli Run Technology Co., Ltd. presents the premium Electromagnetic Pure Iron Cold Rolled Thin Sheet DT4C – engineered specifically for applications demanding exceptional magnetic performance. This 0.5mm thick specialized material delivers minimal core losses and maximum magnetic flux density, making it ideal for precision electromagnetic components in industrial and scientific equipment.
Core Advantages:
- ▲ Superior Magnetic Properties: Achieves high permeability (μmax ≥ 0.0075 H/m) and saturation induction (≥1.4T) for efficient energy transfer
- ▲ Ultra-Low Iron Loss: Reduces eddy current losses by up to 30% compared to standard electrical steels
- ▲ Precision Thickness Control: ±0.02mm tolerance ensures consistent performance in stacked laminations
- ▲ Exceptional Surface Quality: Cold-rolled finish minimizes air gaps in core assemblies

- ✓ High-frequency transformer laminations
The DT4C cold-rolled thin sheet offers significant cost savings over alternatives like permalloy while maintaining comparable magnetic characteristics. Its excellent machinability allows for precision stamping and laser cutting without compromising magnetic properties. For critical electromagnetic applications where performance consistency is paramount, this material provides reliable batch-to-batch uniformity.
Frequently Asked Questions:
Q1: What is the maximum operating temperature for DT4C material?
A: DT4C maintains stable magnetic properties up to 150°C, making it suitable for most industrial environments.
Q2: Can this material be annealed after machining?
A: Yes, stress-relief annealing at 750-850°C in hydrogen atmosphere can restore magnetic properties after forming.
Q3: What surface treatment options are available?
A: Standard mill finish is provided, with optional insulating coatings (e.g. C-5, A-5) available upon request.
Q4: How does DT4C compare to M-19 electrical steel?
A: DT4C offers approximately 15-20% higher saturation flux density with comparable core loss at 60Hz.
Q5: What packaging options ensure material protection?
A: We provide VCI-coated waterproof packaging with edge protectors on wooden pallets for international shipments.
