Product Overview
Engineered Pure Iron for Precision Manufacturing
We supply industrial-grade pure iron (Fe ≥99.8%) in over 12 physical forms optimized for machining, cold working, and component fabrication. Unlike alloy steels, our pure iron delivers predictable performance in critical applications requiring magnetic consistency or corrosion resistance.

- Energy: Forged pure iron anodes for cathodic protection
Q: Which grade prevents edge cracking during stamping?
A: A: Our DT-4 grade (Fe≥99.95%) with controlled Mn/P ratio achieves 38% elongation - ideal for deep-drawn enclosures.
Q: How do your bars minimize magnetic distortion after machining?
A: All bars undergo stress-relief annealing (730°C/6hrs) to maintain µr stability within ±5%. Certification includes post-machining BH curve data.
Q: Can pure iron replace electrolytic iron powder in composites?
A: Yes. Our gas-atomized powder (D90<45μm, O₂<800ppm) offers 20% higher compressibility. Available with phosphate coating for binderless compaction.
Q: What's your solution for welding porosity issues?
A: Our WELD-PRO grade features deoxidizers (Al/Ti) with O₂<50ppm. Reduces slag inclusion by 90% per AWS D1.1 tests. Includes welding procedure specs.
