Medical Grade Titanium Rod

Medical Grade Titanium Rod Description

Medical grade titanium and its alloys have a significantly higher strength to weight ratio than competing stainless steels. The range of available titanium alloys enables medical specialists and designers to select materials and forms closely tailored to the needs of the application. The full range of materials reaches from high ductility commercially pure titanium used where extreme formability is essential, to fully heat treatable alloys with strength above 1300 MPa (190 ksi). Shape-memory alloys based on titanium, further extend the range of useful properties and applications. A combination of forging or casting, machining and fabrication are the process routes used for medical products. Surface engineering frequently plays a significant role, extending the performance of titanium several times beyond its natural capability.

Grades of Medical Grade Titanium

Titanium is available in four different pure titanium grades and as many as 25 different alloys. Below is a sample of the kinds of titanium used in healthcare today:

● 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.
