2. Advantages vs. International Standards
This EN 3.7164 Ti-6Al-4V titanium alloy powder fully complies with EN ISO 5832-3 (European medical implant titanium standard), EN 3.7164 (European material designation) and GB/T 3620.1 (Chinese standard), while exceeding key specifications:
- ✅ Ultra-low oxygen content (O ≤ 0.12%) — well below the standard limit of 0.20%, minimizing embrittlement risk;
- ✅ High sphericity (≥0.9) & excellent flowability (≤35 s/50g) — ensures uniform powder recoating and stable melt pool dynamics in SLM/EBM;
- ✅ High apparent density (≥2.4 g/cm³) and tap density (≥2.8 g/cm³) — approaching theoretical maximum (~3.0 g/cm³), enabling >99.5% relative density in printed parts;
- ✅ Outstanding mechanical properties: UTS ≥950 MPa, YS ≥900 MPa (vs. typical annealed values of ~895/825 MPa), indicating superior microstructure integrity and low defect density;
- ✅ Optimized particle size distribution (D50 = 30–40 μm) — specifically engineered for industrial LPBF systems, balancing spreadability and laser absorption.
This powder is ideal not only for structural components but also for high-reliability medical implants and aerospace critical parts, where performance consistency is great.

|---|---|---|---|
| Al Content | 5.5–6.75% | 5.5–6.75% | 5.5–6.8% |
| V Content | 3.5–4.5% | 3.5–4.5% | 3.5–4.5% |
| Fe Max | ≤0.30% | ≤0.40% | ≤0.30% |
| C Max | ≤0.08% | ≤0.08% | ≤0.10% |
| O Max | ≤0.20% | ≤0.20% | ≤0.20% |
| H Max | ≤0.015% | ≤0.015% | ≤0.015% |
| Medical Use Requirement | EN ISO 5832-3 specifically designed for surgical implants, with stricter purity and biocompatibility requirements | ASTM F136/F3001 explicitly defines implant-grade requirements | No dedicated grade (requires separate certification) |
4. Application Fields of EN 3.7164 Titanium Alloy
EN 3.7164 (Ti-6Al-4V), widely recognized across the European Union as a premium α+β titanium alloy, dominates high-performance industries thanks to its exceptional strength-to-weight ratio, corrosion resistance, biocompatibility, and processability. In aerospace, it is employed in landing gear, compressor blades, and airframe fittings; in medical devices, it forms the backbone of permanent implants including hip/knee joints, dental implants, and trauma fixation systems; in energy & chemical processing, it enables durable heat exchangers, reactors, and deep-sea pipelines; and in consumer premium sectors, it powers lightweight golf club heads, bicycle frames, and automotive performance components. With additive manufacturing, EN 3.7164 unlocks unprecedented design freedom—enabling topology-optimized, biomimetic, and multifunctional integrated structures that align with the European Green Deal manufacturing initiatives.
