Aerospace-Grade Pure Iron Rods | Beilun Metal
Ultra-High Strength Pure Iron Rods for Critical Aerospace Load-Bearing Assemblies
Product Overview
Beilun Metal's aerospace-grade Pure Iron Rods are engineered to withstand hypervelocity stresses and cryogenic-to-hypersonic thermal cycles. Featuring 99.97%+ purity and directionally solidified grain structures, our rods deliver anisotropic strength (UTS ≥580MPa) for rocket engine mounts, satellite truss joints, and reusable launch vehicle (RLV) landing gear. Compliant with AMS 2301 and ESA ECSS-Q-ST-70-71 standards.

FAQ
Q: How do your rods prevent hydrogen-assisted cracking in LH2 systems?
A: Our proprietary vacuum degassing reduces H₂ to <0.1ppm, with TiC dispersion traps to block crack propagation.
Q: Can you match legacy alloys for heritage spacecraft upgrades?
A: Yes – Reverse-engineered compositions available for Apollo-era spec equivalency (e.g., MSFC-SPEC-250).
Q: Do you supply flight-qualified lot traceability?
A: Full DNV GL-certified traceability from ingot to final rod (heat code, processing history, NDT records).
Q: MOQ for prototype struts?
A: R&D batches from 20kg with AMS 2750 pyrometry reports.
