Ti-6Al-2Sn-4Zr-2Mo vs Ti-6Al-4V (Grade 5): 85% composition overlap. Some similarities but notable differences in alloying elements.
Ti-6Al-2Sn-4Zr-2Mo vs Ti-6Al-4V (Grade 5)
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.
Ti-6Al-4V (Grade 5)
3.7164
The most widely used titanium alloy — accounts for ~50% of all titanium production. Alpha-beta alloy with exceptional strength-to-weight ratio. Used for jet engine components, airframe structures, medical implants (hip/knee), fasteners, and racing components. Biocompatible.
