Hot Rolled Pure Iron Wire Rod
High Purity, Consistent Coil Dimensions for Cold Drawing & Electrode Manufacturing
Product Overview
Hot rolled pure iron wire rod is the preferred feedstock for downstream processes such as wire drawing, mesh weaving, and electrode manufacturing. Unlike hot rolled bars (which are straight lengths) or cold drawn wires (which are already processed), our wire rod is delivered in coils, allowing you to feed it directly into draw benches or continuous annealing lines.
As the actual manufacturer, we control the entire route: electrolytic iron melting → billet casting → reheating → continuous hot rolling (13–19 passes) → water cooling to control scale → coiling. This integrated process ensures uniform chemical composition, consistent mechanical properties, and scalable supply for industries requiring pure iron in high volumes.
Key Features
| Feature | Benefit |
|---|---|
| Hot rolled, not cold drawn | Lower cost, softer condition, easier to draw to fine diameters |
| High purity (≥99.9%) | Ultra‑low carbon, low sulfur and phosphorus for clean melting applications |
| Coil form | Continuous length (≥500 m per coil) reduces rewinding waste |
| Typical diameter range | Φ5.5 mm – 20 mm (common sizes in stock) |
| Low surface decarburization | Minimal carbon loss at surface, maintains magnetic properties |
| Good surface condition | Scale removable by pickling or mechanical descaling before drawing |
| Factory direct | Competitive pricing, large coil weights, short mill lead times |
Why Choose Our Hot-Rolled Pure Iron Wire Rod?
Consistent Raw Material Properties
Our wire rod is specifically designed to achieve a reduction ratio of up to 99% when drawing fine-diameter wire (0.1–2 mm) without the need for intermediate annealing. Its low impurity content (particularly non-metallic inclusions) reduces die wear and wire breakage, thereby increasing your production output.
Ideal for Welding Electrode Cores
Low-carbon steel electrodes (such as E6013 and E7018) require pure iron core wire with strictly controlled carbon content (≤0.01%) and minimal residue. Our wire far exceeds these requirements, delivering stable arc characteristics and minimizing spatter.
Magnetic Component Applications
After cold drawing and annealing, pure iron wire is suitable for magnetic sensors, relay springs, and electromagnetic shielding braided mesh. Hot-rolled wire features a uniform microstructure, ensuring consistent magnetic response.

Frequently Asked Questions
Q: What is the typical purity of your pure iron wire rod?
A: Our standard grade guarantees Fe ≥ 99.9% with total impurities <0.1%. For high‑purity requirements (e.g., 99.95%, 99.99%), we supply a premium grade – please inquire.
Q: Do you offer diameters smaller than 5.5 mm?
A: We produce hot rolled rod down to 5.0 mm. For diameters under 5 mm, we recommend cold drawn wire (which we also supply – contact us for options).
Q: Is the surface scale harmful for drawing?
A: For most drawing operations, the scale is removed by acid pickling or mechanical descaling (e.g., shot blasting) before the first die. We provide detailed descaling recommendations. Alternatively, we can supply pickled and coated (lime/borax) rod at additional cost.
Q: Can you supply wire rod with low carbon for deep drawing?
A: Yes. Our standard carbon is ≤0.003%. For applications requiring even lower carbon (≤0.0015%), we offer a special grade.
Q: What is your MOQ for wire rod?
A: MOQ is 20 tons (one 20' container) for standard diameters. Sample coils (1‑2 tons) are available for testing – please discuss.
Q: Q: Do you provide magnetic property testing on wire rod?
A: A: Yes. For customers who will draw and anneal the wire for magnetic applications, we can supply test coupons from the same heat, along with annealing recommendations and expected magnetic performance (Hc, μ, Bs).
