Ti-5Al-5V-5Mo-3Cr (Ti-5553)
Near-beta high-strength titanium alloy developed by VSMPO-AVISMA. Rm ~1250 MPa, Rp0.2 ~1170 MPa, A ~6–8%. Density 4.62 g/cm³. Deep section hardenability superior to Ti-10-2-3. Boeing selected for 787 Dreamliner landing gear and other structural forgings. Better forgeability window than Ti-10-2-3. Applications: large structural forgings for landing gear, flap tracks, wing spars, helicopter components.

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.
