The Alloy Smelter's Advantage
When your business is producing high-performance alloys, the quality of your raw material determines the quality of your finished product. Our pure iron billets are engineered to be the ideal melt stock because they offer:
Fast, Predictable Melting: Hot-rolled dense structure with minimal surface oxide means rapid melt-down and consistent bath chemistry.
Cleaner Final Alloys: Ultra-low tramp elements (Pb, Sn, Sb, Bi) reduce the risk of inclusions and grain boundary segregation in your finished alloy.
Consistent Yield: Tight chemistry control batch-to-batch means you adjust your recipe less and trust your base material more.
Reduced Oxidation Loss: Low surface area-to-volume ratio compared to scrap or loose fines minimizes melt loss and dross formation.
Target Chemistry for Your Alloy System
We understand that different alloy systems require different base iron characteristics. We tailor our production to match your target alloy's requirements:
| Your Alloy Type | Ideal Billet Chemistry Focus | Why It Matters |
|---|---|---|
| Nickel-Iron (NiFe) Magnetic Alloys | C ≤ 0.005%, S ≤ 0.002%, Mn controlled | Prevents carbide and sulfide formation that disrupts magnetic permeability |
| Cobalt-Iron (CoFe) High Saturation Alloys | High purity base (Fe ≥ 99.8%), low Al | Aluminum forms non-metallic inclusions that reduce mechanical ductility |
| Invar & Expansion Alloys | Tight C and Mn ranges, low residual elements | Ensures precise thermal expansion coefficient control |
| Soft Magnetic Stainless Steels | Ultra-low C + N (≤ 80 ppm combined) | Essential for corrosion resistance and magnetic softness after annealing |
| Electrical Resistance Alloys | Consistent Si and Mn levels, controlled residuals | Maintains stable resistivity values in final product |
Hot Rolled for Smelting Efficiency
Our billets are not just chemically pure-they are physically optimized for furnace charging:
Optimized Density: Solid billet form sinks readily in induction furnace baths without bridging.
Clean Surface: Hot rolling removes primary scale; we can pickle or dress billets for ultra-clean applications upon request.
Cut-to-Weight Options: We can cut billets to specific weight increments to simplify furnace charge calculation and reduce handling time.
Frequently Asked Questions
Q: What is the typical melting behavior of your billet in an induction furnace?
A: Our hot-rolled billets have a dense structure and melt smoothly without excessive sparking or oxidation. They sink well in the bath and have a predictable liquidus temperature (~1535°C) that allows accurate superheat control.
Q: Can you guarantee low residuals like lead, tin, and antimony?
A: Yes. We understand these elements are harmful in final alloys. We use selected pure scrap and virgin iron sources to keep residuals below 0.005% each. Our certificate includes these elements upon request.
Q: Do you offer billets specifically for vacuum induction melting (VIM)?
A: Absolutely. For VIM applications, we can supply billets with guaranteed low gas content (O ≤ 20 ppm, N ≤ 30 ppm) and minimal volatile residuals. These are packaged to prevent contamination before charging
