High-Purity Iron: The Backbone of Advanced Technology and Precision Manufacturing
Introduction
High-purity iron (HPI) has emerged as a cornerstone material for cutting-edge industries requiring exceptional chemical stability, magnetic properties, and corrosion resistance. At Beilun Metals, we specialize in delivering premium-grade iron solutions that meet stringent international standards for purity and performance.
What is High-Purity Iron?
High-purity iron refers to iron with **99.95% (4N) to 99.9999% (6N) purity**, achieved through advanced refining processes like **electron beam melting (EBM)** and **zone refining**. Key characteristics include:
- Ultra-low impurity levels (<50 ppm for 4N grade)
- Enhanced magnetic permeability
- Superior electrical conductivity
- Reduced oxide inclusions
Key Grades :
- **4N Iron (99.99%)**: Widely used in specialty alloys and vacuum systems
- **5N Iron (99.999%)**: Critical for semiconductor manufacturing
- **6N Iron (99.9999%)**: Reserved for quantum computing and nuclear applications
Manufacturing Process of High-Purity Iron
1.Electrolysis : Raw iron undergoes electrolytic refining to remove base impurities.
2. Vacuum Induction Melting (VIM)**: Eliminates gaseous contaminants (O₂, N₂).
3. Electron Beam Melting (EBM)**: Final purification step achieving <1 ppm residual elements.
4. Ultra-Precision Rolling**: Produces foil, wire, and sputtering targets with nanoscale surface finishes.
Quality Control
- ICP-MS (Inductively Coupled Plasma Mass Spectrometry) for trace element analysis
- GDMS (Glow Discharge Mass Spectrometry) certification
- Compliance with **ASTM B933** and **ISO 16112** standards
Applications of High-Purity Iron
1. **Semiconductor Industry**
