Titanium
Titanium combines high strength with low weight and excellent corrosion resistance. Grade 2 is the common commercially pure grade; Grade 5 (Ti-6Al-4V) is the high-strength alloy for aerospace, medical and high-performance parts.
When to Choose Titanium
- Strength-to-weight ratio is critical
- Seawater or chemical corrosion is a risk
- The part is for aerospace, medical or marine use
- Biocompatibility is required
