Grades of Medical Titanium

Titanium can be found in a wide array of biomedical implants such as pacemakers, eye implants, and hearing aids.

Titanium possesses a unique ability to bind with bone and living tissue, making it an ideal material for orthopedic implants such as knee and hip replacements. Because of its strength and increased resistance to corrosion, it is well-suited to many other medical instruments, as well.

  • Pure Titanium
The four grades of pure titanium are numbered 1-4, with 1 being the softest and 4 being the strongest. Grades 1, 2, and 4 are most commonly found in modern medical devices. Each is distinguished by its degree of formability and ductility.
  • Grade 1
Grade 1 titanium consists of pure, unalloyed titanium. It is prized in healthcare for its excellent formability, increased resistance to corrosion, and resilience against impact.
  • Grade 2
Grade 2 titanium is an unalloyed form of titanium with greater strength than Grade 1.
  • Grade 4
Grade 4 titanium is another form of unalloyed titanium. Like Grades 1 and 2, it offers enhanced resistance to corrosion, great formability, and high strength.
  • Grade 5
Grade 5 titanium is an alloy made with 6% aluminum and 4% vanadium. Since it offers superior fracture resistance, it is the most common material used in dental implants.
  • Grade 7
Grade 7 titanium consists of titanium alloyed with 0.12% to 0.25% palladium. It is more resistant to corrosion than any other titanium alloy.
  • Grade 9
Grade 9 titanium is an alloy made with 3% aluminum and 2.5% vanadium. It is particularly known for its great mechanical strength.
  • Grade 11
Grade 11 contains unalloyed titanium as well as 0.12% to 0.25% palladium, much like Grade 7 titanium. It shares many properties with Grade 1 titanium, but it offers superior resistance to corrosion.
  • Grade 23
Grade 23 titanium is an alloy made with 6% aluminum and 4% vanadium that features extra low interstitial elements. Like Grade 5 titanium, it is also a common choice for dental implants.
