6. FAQs
Q: How do pure iron ingots differ from steel?
A: Pure iron contains <0.02% carbon and no alloying elements, offering superior soft magnetic properties compared to steel.
Q: Can these ingots be directly cast into final parts?
A: Yes – their low gas content and homogeneous structure enable near-net-shape casting with minimal machining.
Q: What's the shelf life?
A: Properly stored in dry conditions, ingots retain quality for >5 years.
