Why Choose Our VIM-Melted Soft Magnetic Iron Bars?
At Xtairon, we pioneer the production of soft magnetic iron bars through advanced Vacuum Induction Melting (VIM) technology. Designed for industries requiring minimal hysteresis loss, high permeability, and exceptional thermal stability, our iron bars set the benchmark for precision and reliability.
Key Advantages of VIM Technology:
Ultra-High Purity (99.98%+): Eliminates oxygen, nitrogen, and gaseous impurities for flawless magnetic performance.
Precise Alloy Control: Adjust trace elements (C, S, P) to <10 ppm for customized permeability and coercivity.
Zero Contamination: Crucible-free melting ensures no foreign material infiltration.
Critical Soft Magnetic Properties of VIM-Melted Iron
Soft magnetic materials thrive on purity and structural integrity. Below is how our VIM-processed iron outperforms conventional alternatives:
| Property | Our VIM Iron Bars | Standard Induction-Melted Iron |
|---|---|---|
| Purity (%) | 99.98% - 99.995% | 99.5% - 99.8% |
| Carbon Content | ≤0.005% | 0.02% - 0.08% |
| Coercivity (Hc) | ≤50 A/m | 80 - 120 A/m |
| Relative Permeability | 200,000 μH/m (max) | 100,000 - 150,000 μH/m |
| Hysteresis Loss (60Hz) | 1.5 W/kg | 3.0 - 4.5 W/kg |
Why These Metrics Matter:
Ultra-Low Coercivity: Minimizes energy loss in alternating magnetic fields, ideal for transformers and inductors.
Near-Zero Impurities: Enhances magnetic saturation (up to 2.2 Tesla) for compact component designs.
Superior Thermal Stability: Performs reliably from -50°C to 400°C without magnetic degradation.
Applications of VIM Soft Magnetic Iron Bars
Our bars are engineered for industries where precision and efficiency are non-negotiable:
| Industry | Application | Key Benefit |
|---|---|---|
| Power Electronics | High-frequency transformers, chokes | Reduced eddy current & hysteresis loss |
| EV & Hybrid Systems | Motor laminations, onboard inverters | Lightweight, high flux density |
| Aerospace | Actuators, sensor cores | Stability under extreme temperatures |
| Medical Devices | MRI magnet yokes, radiation shielding | Biocompatible, zero magnetic noise |

FAQ Section
Q: Can you produce iron bars with <5 ppm sulfur content?
A: Absolutely. Our VIM process achieves sulfur levels as low as 2 ppm for ultra-low distortion applications.
Q: Do you provide magnetic property curves (B-H curves)?
A: Yes. Each order includes a detailed B-H curve and loss data at specified frequencies.
Q: What's the minimum order quantity for custom grades?
A: MOQ starts at 1 ton for standard grades, 2 tons for custom alloys.
Package
Pure iron is typically packaged with rust-preventive oil, wrapped in plastic film, and secured with plastic or metal straps. It is then placed on wooden pallets or in wooden crates, sometimes using moisture-proof paper or vacuum packaging for extra protection during transportation and storage.
