Ti Grade 12
Titanium alloy with 0.3% Mo + 0.8% Ni — improved crevice and reducing-acid corrosion resistance over CP grades. Strength similar to Grade 2 but much better in chemical environments containing hot brines and reducing acids. More cost-effective than Grade 7 (Pd). Used for heat exchangers, pressure vessels, and chemical processing equipment in corrosive service.

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.
