Medical Grade Titanium Foil

Medical Grade Titanium Foil Description

Titanium is a transition metal. It is present in several minerals including rutile and ilmenite, which are well dispersed over the Earth's crust. Even though titanium is as strong as some steels, its density is only half of that of steel.

The list of titanium benefits is lengthy. This makes it incredibly useful for a number of different industries, including the automotive, aerospace and architectural worlds. But because titanium resists corrosion, is biocompatible and has an innate ability to join with human bone, it has become a staple of the medical field, as well. From surgical titanium instruments to orthopedic titanium rods, pins, plates and foils, medical and dental titanium has truly become the fundamental material used in medicine.

Properities of Medical Grade Titanium

● Durability

● Higher strength-to-weight ratio

● Non-ferromagnetic property

● Biocompatibility

● Biointerfacing

● Osseointegration

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.
