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 1
3.7025The softest and most ductile commercially pure titanium grade. Lowest O content (0.18% max) for maximum formability. Used for plate heat exchangers, chemical plant vessels, explosive cladding, deep-drawn parts, and anodizing applications. Lower strength than Grade 2 but superior formability.
Titanium Grade 4
3.7065The strongest commercially pure titanium grade. Highest oxygen content (0.40% max) for maximum strength among CP grades. UTS min 550 MPa — approaches some Ti alloys. Used for airframe skins, marine hardware, surgical implants, and chemical plant components requiring higher strength than Grade 2.
Ti Grade 9 / Ti-3Al-2.5V
3.7195Medium-strength alpha-beta titanium alloy — the standard for seamless tubing. 50% stronger than CP Grade 2 with better cold formability than Ti-6Al-4V. The go-to alloy for hydraulic tubing in aerospace and bicycle frames. Used for aircraft hydraulic lines, offshore risers, and sporting goods.
