What Are Pure Iron Tubes?
Pure iron tubes and pipes are specialized metallic products crafted from iron with a minimum purity of 99.95% iron (Fe), making them one of the most chemically refined iron products available. Unlike standard steel or alloy pipes, these tubes contain negligible impurities (e.g., carbon, sulfur, phosphorus), ensuring exceptional electrical conductivity, thermal stability, and corrosion resistance. Their uniform microstructure and minimal defects make them ideal for industries requiring precision and reliability.
Ingredients & Manufacturing Process
Our pure iron tubes are produced through a multi-stage vacuum induction melting (VIM) process, followed by extrusion or cold drawing to achieve precise dimensions. The composition is strictly controlled to ensure:
Iron (Fe): 99.95% minimum
Trace Elements: Carbon (C) ≤ 0.005%, Sulfur (S) ≤ 0.002%, Phosphorus (P) ≤ 0.002%
No Added Alloys: 100% iron base for unmatched material consistency.

FAQ: Top Engineer & Buyer Queries
Q: Can pure iron tubes replace copper in electrical conduits?
A: Yes! With **electrical resistivity of 0.11 μΩ·m** (vs. 0.17 μΩ·m for copper), they offer 35% higher conductivity than standard steel, ideal for grounding cables and power rails.
Q: How to prevent rust in humid environments?
A: Specify phosphated or galvanized tubes-salt spray resistance exceeds 500 hours vs. 200 hours for uncoated iron.
Q: Minimum bend radius for cold forming?
A: 1x tube diameter (e.g., 10mm tube = 10mm radius). For complex shapes, anneal at 780°C post-bending.
Q: How does purity affect performance?
A: Higher purity reduces impurities that can cause brittleness or corrosion, extending product lifespan by up to 40% in harsh environments.
Q: Do you offer samples for testing?
A: Absolutely-contact us for free samples (shipping fees may apply).
