Reliable Base Metal for Everyday Industrial Use
Our Commercial Pure Iron (CPI) delivers essential iron properties at 40% lower cost than premium grades. With controlled residuals and proven consistency, it's engineered for structural components, fabrication projects, and non-critical parts where ultra-purity isn't required.

Q: Can I achieve Ra 3.2μm surface finish?
A: Yes. With proper feeds/speeds: - Turning: 120m/min, feed 0.15mm/rev - Milling: Carbide tool, 0.05mm DOC
Q: How does CPI perform in cold heading?
A: Optimal for M6-M12 fasteners. Annealed hardness 55 HRB max ensures ≤3% scrap rate.
Q: What's your solution for welding porosity?
A: Use ER70S-6 wire with 20-25 L/min CO₂ flow. Pre-clean oil with acetone (no grinding needed).
Q: Do you supply ready-to-paint material?
A: Stock items come with light oil coating. Specify "pickled & oiled" for painting prep .
