FAQ
Q1: How does Ti-6Al-4V differ from Grade 2 titanium in medical applications?
A: Ti-6Al-4V offers 3x higher strength and osseointegration compatibility for implants, while Grade 2 excels in chemical corrosion resistance for non-load-bearing parts.
Q2: What machining parameters prevent tool wear?
A: Use carbide tools at low speeds (30–60 m/min) with high-pressure coolant to minimize galling and heat buildup.
Q3: Are bars certified for aerospace structural components?
Full compliance includes:
- AMS 4928 (Aerospace Material Specification)
- ASTM F136 (Medical Grade 5)
- NACE MR0175/ISO 15156
