As a materials engineer with 15+ years in medical titanium alloys, I'm often asked about ASTM F136. Let me break down this "gold standard" implant material in simple terms.
What is titanium 6AL-4V per ASTM F136?
ASTM F136 defines the 6AL-4V ELI alloy - the top choice for orthopedic/dental implants. Last year, we used it for a 65-year-old's hip replacement. He was golfing in 3 months! That's the power of:
Ultra-low interstitial (ELI) design
Optimized Al (5.5-6.5%) and V (3.5-4.5%)
Purer than industrial 6AL-4V
What is ASTM F136 titanium?
Think of ASTM F136 as the "Michelin star" for medical titanium. Our weekly tests include:
| Test | Requirement | Typical Value |
|---|---|---|
| Oxygen | ≤0.13% | 0.10% |
| Iron | ≤0.25% | 0.18% |
| Nitrogen | ≤0.05% | 0.03% |
Is it implant grade?
Absolutely! 75% of joint replacements (2 M+ surgeries) use it because:
"It's tailored for the body - strong enough to bear weight, light enough not to stress bones, and nearly rejection-proof." - Dr. Smith, Orthopedic Surgeon
Key advantages:
✓ Fatigue strength >500MPa
✓ Perfect osseointegration
✓ Near-zero allergic reactions
What is Ti-6AL-4V?
"Imagine a material 40% lighter than steel but just as strong, MRI-compatible, and bonds permanently with bone - that's 6AL-4V." - Our R&D Director
Comparison:
| Property | Industrial | ASTM F136 ELI |
|---|---|---|
| Oxygen | ≤0.20% | ≤0.13% |
| Applications | Aerospace | Implants |
| Price | $ | $$$ |
| Certifications | Basic | Biocompatibility |
Pro Tips for Buyers:
Always request ASTM F136 Mill Certs
Verify FDA/CE certifications
Require biocompatibility reports
Remember: Medical-grade costs 2 -3x more, but for patient safety, it's worth every penny. Need specs or advice? Our engineers are here to help. When lives are at stake, never compromise on materials.
