Ti-6Al-7Nb
Alpha-beta titanium alloy with Nb replacing V — developed specifically to eliminate vanadium cytotoxicity concerns. Similar mechanical properties to Ti-6Al-4V but with superior biocompatibility and corrosion resistance in body fluids. ISO 5832-11 / ASTM F1295 for surgical implants. Trade name: IMI 367 (originally). Used for hip prostheses, knee replacements, fracture fixation plates, spinal devices, screws, and dental implants.

Ti-6Al-4V (Grade 5)
3.7164The 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.
Titanium Grade 2 (CP)
3.7035The 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.
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.
