Titanium Alloy

Titanium AISI/SAE

Titanium combined with aluminum, vanadium, or other metals to achieve a high strength-to-weight ratio with excellent corrosion resistance.

Titanium alloys offer the highest specific strength of any structural metal — twice that of aluminum and 60% that of steel at half the weight. Combined with exceptional corrosion resistance (virtually immune to seawater and body fluids), titanium serves aerospace, medical, marine, and chemical processing industries despite its higher cost.

Designation Guide

Titanium alloys are classified by crystal structure: alpha (CP grades 1-4, most corrosion resistant), near-alpha (Ti-5Al-2.5Sn, creep resistant), alpha-beta (Ti-6Al-4V, most widely used), and beta (Ti-10V-2Fe-3Al, highest strength). ASTM grades 1-4 are commercially pure with increasing oxygen content and strength. Grade 5 (Ti-6Al-4V) accounts for over 50% of all titanium alloy production.

Selection Tips

Ti-6Al-4V (Grade 5) is the default for structural aerospace components and medical implants. For better formability and weldability, consider Grade 2 CP titanium. Grade 23 (Ti-6Al-4V ELI) is mandatory for medical implants due to lower interstitial content. For seawater service, Grade 2 provides excellent resistance at lower cost than nickel alloys. Beta alloys (Ti-15-3, Beta C) offer cold formability for springs and fasteners.
