Frequently Asked Questions
Q: How does Grade 9 compare to Grade 5 titanium?
A: Grade 9 offers better formability than Grade 5 at lower cost, with about 70% of its strength.
Q: Can Grade 9 be welded?
A: Yes - it welds similarly to pure titanium using GTAW with proper shielding.
Q: What's the maximum working temperature?
A: 600°F (315°C) for continuous service, higher for short-term exposure.
Q: Is passivation required for medical use?
A: Recommended - we offer medical-grade passivation per ASTM F86.
Q: Do you supply small diameter tubing for medical devices?
A: Yes - we specialize in precision tubing down to 1mm OD.
