Frequently Asked Questions (Advanced)

1) What powder specifications matter most when using FeSiCr powder for Network System components?

• Prioritize particle size distribution aligned to the process (e.g., 15–45 µm for LPBF, 45–106 µm for DED/Binder Jetting), high sphericity for flowability, oxygen content typically ≤ 0.10–0.20 wt% depending on route, low carbon/sulfur to protect oxidation resistance, and consistent apparent/tap density. Track Hausner ratio ≤ 1.25 for reliable recoating.

2) How does FeSiCr compare to copper- or aluminum-based materials for busbars in network power distribution?

• Copper and aluminum outperform FeSiCr in electrical conductivity, but FeSiCr offers better high-temperature oxidation resistance, higher wear strength, and superior hardness. It is often selected for mechanically demanding connectors, sliding contacts, EMI/EMC hardware, and thermally stressed fixtures rather than primary high-current conductors.

3) Is FeSiCr powder suitable for EMI/RFI shielding parts inside data centers and telecom racks?

• Yes. FeSiCr’s ferromagnetic/paramagnetic behavior (tunable via Si/Cr content and heat treatment) supports magnetic loss mechanisms that can improve mid- to high-frequency EMI attenuation. Hybrid designs combine FeSiCr with Cu/Ni plating or conductive gaskets to balance shielding effectiveness and contact resistance.

4) What post-processing steps most improve FeSiCr AM parts for network hardware?

• Stress relief to stabilize microstructure, hot isostatic pressing (HIP) for porosity closure on fatigue-critical parts, surface finishing (shot peen/bead blast + machining/electropolish) to reduce roughness in contact areas, and protective coatings (Ni, NiP, or Cr) to optimize corrosion/oxidation and contact resistance.

5) How should powder reuse be controlled in serial production?

• Apply digital powder passports per ISO/ASTM 52907, sieve every cycle, blend 20–50% virgin powder, and set stop criteria: oxygen rise > 0.02 wt% from baseline, Hausner > 1.25, Hall flow drift > 15%, or PSD tails out of spec. Maintain dry, inert storage to limit oxide growth between builds.

2025 Industry Trends

• AM-first network hardware: Data center OEMs validate FeSiCr for complex EMI/EMC brackets, airflow-optimized heat sink frames, and ruggedized connector housings produced by LPBF/Binder Jetting.
• Oxidation/EMI co-optimization: Heat-treatment windows and plating stacks (Ni strike + Sn/Ag or NiP) tuned for both high-temp oxidation resistance and stable contact resistance.
• Traceability and QA: Digital material passports linking FeSiCr powder lots, reuse cycles, O/N content, and in-situ AM telemetry are now common in critical network infrastructure bids.
• Sustainability: Recycled-content declarations (≥40–60% Fe input) and inert gas recirculation in atomization lines reduce embodied footprint for FeSiCr powder.
• Inline sensing: Optical/acoustic PSD monitoring and inline O2/H2O sensors at atomizers improve lot-to-lot consistency for AM-grade FeSiCr.
