Product Introduction
Foundry-Grade Pure Iron: The Critical Base Metal for Demanding Applications
As a leading pure iron manufacturer with ISO 17025-certified labs, we produce ultra-high purity iron (99.99%+) specifically engineered for foundry and metallurgical processes. Unlike commercial pure iron, our foundry-grade variant features controlled residuals critical for defect-sensitive operations.

Why Our Foundry-Grade Iron Outperforms
①Defect Mitigation Technology
Proprietary vacuum degassing and ESR (Electroslag Remelting) processes achieve ultra-low gas content (<15ppm H₂, <45ppm N₂), directly addressing:
- Reduced slag formation in investment casting
- Improved surface finish in thin-wall castings
②Consistency Guaranteed
Automated continuous casting with real-time spectral analysis ensures:
- Deviation of key elements <±0.0008% between batches
- Uniform density (7.87 g/cm³ ±0.01)
③Application-Optimized Formats
- Ingots: 5kg-500kg (Square/Round)
- Granules: 1-5mm (For rapid alloying)
- Custom-cut pieces (Pre-weighed charges)

FAQ
Q: How does your low-sulfur content benefit ductile iron production?
A: Sulfur levels <30ppm minimize Mg consumption during nodularization, resulting in tighter graphite distribution (Type I/II) and 15% higher elongation vs. standard pure iron.
Q: Can you match specific electromagnetic properties?
A: Yes. Through controlled silicon residuals (<0.008%), we customize iron permeability (μmax up to 150,000) and coercivity (<80 A/m). Provide your target BH curve parameters.
Q: What packaging prevents oxidation during transit?
A: We offer triple-layer protection: VCI paper wrapping + desiccant + argon-filled sealed drums. Guaranteed surface oxidation <5μm after 6-month storage.
Q: Do you supply vacuum-melted grades?
A: Our VIM (Vacuum Induction Melted) grade achieves O₂<20ppm and inclusion rating ≤0.5 per ASTM (Bifilm index <2mm/kg). Available for aerospace AMS specs.
Q: How do you handle traceability?
A: Each batch receives a unique QR-coded MTR including melt parameters, SEM inclusion maps, and ICP-MS impurity reports. Digital archives maintained for 20 years.
