Ti-6Al-2Sn-4Zr-2Mo vs Titanium Grade 2 (CP): 81% composition overlap. Some similarities but notable differences in alloying elements.
Ti-6Al-2Sn-4Zr-2Mo vs Titanium Grade 2 (CP)
Side-by-side chemical composition and mechanical property comparison.
Overview
Ti-6Al-2Sn-4Zr-2Mo
Near-alpha high-temperature titanium alloy. Better creep resistance than Ti-6Al-4V at temperatures above 400°C — usable to 550°C continuous. Sn and Zr are alpha-stabilizers providing solid-solution strengthening without eutectoid decomposition. THE jet engine compressor disc alloy (stages 2-7 typically). Also used for afterburner structures, blisks, and gas turbine components. Si addition (0.06-0.10%) further improves creep.
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.
