Titanium Alloy Materials

Titanium alloys combine 40% lower density than steel with corrosion immunity (self-healing TiO₂ passive film) and biocompatibility. Ti-6Al-4V (Grade 5, 880 MPa yield) dominates aerospace and medical implant applications. Commercially pure grades (Grade 1–4) provide graduated strength for chemical processing and marine service. Key limitations: poor tribological properties requiring surface treatments, difficult machinability (low thermal conductivity), and high cost (10–20× carbon steel). Near-alpha alloys (Ti-6242) extend service to 540°C for jet engine hot sections.
