FAQ
Q1: How does TA1 differ from TA2 or TC4 titanium bars?
A: TA1 (Grade 1) prioritizes maximum ductility and corrosion resistance, while TA2 (Grade 2) offers higher strength, and TC4 (Grade 5) is a Ti-6Al-4V alloy for extreme mechanical loads.
Q2: What machining parameters prevent galling?
A: Use carbide tools at cutting speeds ≤60 m/min with high-pressure coolant (≥50 bar) to minimize heat buildup.
Q3: Are bars certified for surgical implants?
Full compliance includes:
- ASTM F67 (Surgical Implant Grade)
- ISO 13485 (Medical Device Quality Management)
- FDA 21 CFR Part 820
Q4: What’s the minimum order quantity (MOQ)?
Standard stock: 1000 kg MOQ.
Custom sizes/surface finishes: 5 tons MOQ (lead time 30 days).
