Ti-6Al-2Sn-4Zr-6Mo vs Titanium Grade 2 (CP): 70% composition overlap. Some similarities but notable differences in alloying elements.
Ti-6Al-2Sn-4Zr-6Mo vs Titanium Grade 2 (CP)
Side-by-side chemical composition and mechanical property comparison.
Overview
Ti-6Al-2Sn-4Zr-6Mo
Beta-rich alpha-beta titanium alloy — higher Mo (6%) than Ti-6242 for significantly higher strength (UTS 1100+ STA). Forged beta then STA (Solution Treat + Age) for peak properties. Used for high-compressor discs and blades in jet engines where strength at 300-450°C is critical. More Beta phase than 6242 = higher strength but lower creep resistance. AMS 4981.
Titanium Grade 2 (CP)
3.7035
The workhorse commercially pure titanium grade. Best balance of strength, ductility, and corrosion resistance among CP grades. Excellent resistance to seawater, chlorides, and oxidizing acids. Used for heat exchangers, chemical processing, marine hardware, desalination, and medical implants.
