Product Overview
Pure Iron for Electromagnetic Applications, also known as electromagnetic pure iron, is a specialized grade of iron engineered for superior soft magnetic properties..Electromagnetic pure iron is a cornerstone material for industries requiring precision magnetic performance, minimal energy loss, and long-term reliability.
Source & Composition
Our pure iron is derived from carefully selected high-grade iron ore, processed in state-of-the-art facilities to ensure consistency and purity. Sourced from high-purity iron ore (Fe₂O₃ >68%) and trusted global suppliers, the raw materials undergo rigorous quality checks to guarantee minimal impurities from the outset.
Composition & Characteristics
Ultra-High Purity: 99.8%~99.95% iron content, with controlled levels of carbon (<0.003%), sulfur, and phosphorus to prevent magnetic aging.
Magnetic Excellence: High initial permeability (μ_i) and saturation induction (B_s) enable efficient magnetic flux density and low core loss.
Stable Performance: Resistant to temperature fluctuations and mechanical stress, ensuring long-term reliability.
Key Composition:Iron (Fe): ≥99.95%,Carbon (C): ≤0.008%,Sulfur (S): ≤0.005%,Phosphorus (P): ≤0.01%,Oxygen (O): ≤20 ppm
Manufacturing Process
1.Vacuum Induction Melting (VIM): Removes gases (O₂, N₂) and volatile impurities under <10⁻³ mbar vacuum.
2.Electroslag Remelting (ESR): Eliminates non-metallic inclusions via CaF₂-CaO-Al₂O₃ slag, achieving ≤5 µm inclusion size.
3.Cold Rolling & Annealing: Produces ultra-thin laminations (0.1–0.5 mm) with controlled grain structure (ASTM No. 6–8).
Key Applications
Power Electronics: High-frequency transformers, inductors, and inverters.
E-Mobility: Electric motors, charging stations, and battery management systems.
Medical Technology: MRI scanners, magnetic therapy devices, and surgical robotics.
Industrial Automation: Sensors, actuators, and shielding in harsh environments.
Renewable Energy: Wind turbine generators and solar inverter cores.
Advantages
Energy Efficiency: Lower core losses reduce operational costs in high-frequency devices.
Design Flexibility: Available in custom shapes, sizes, and grades for specific engineering needs.
Sustainability: Recyclable material with minimal environmental impact, compliant with RoHS and REACH standards.
