Titanium TI-6AL-4V Properties & Common Uses
TI-6AL-4V Grade 5 Titanium: If you find yourself talking about TI-6AL-4V grade 5 titanium… you are talking about the Cadillac of the titanium alloy world. This workhorse alloy is the most commonly used metal in the aerospace, marine, power generation, and offshore industries (just to name a few). Because it is incredibly strong and lightweight, modern manufacturing relies, trusts, and continues to grow due to its durability and mass production.
Titanium is not created equal, and although titanium on a hole is an incredible material, each variation has unique properties and uses. In general, they are broken up into four groups: alpha beta structure, unalloyed titanium, alpha structure, and beta structure. With a wide range of properties, they are each used accordingly for different applications in so many industries, which makes it, hands down, the finest quality metal around.
But we are here to take a very specific look at Ti6Al4V and how it has advanced the way we create and build in so many aspects of today’s world. One of its strengths is that it is heat treatable and can even be welded. Those in the automotive industry have benefited from this particular characteristic for years. It is commonly used because of its exceptional strength, which far exceeds the strength of commercially-pure titanium.
Grade 5 titanium has some unmatched factors, such as:
- Easily welded
- Easily fabricate
- Can withstand temperatures up to nearly 800°
- High strength-to-weight ratio
- Low modulus of elasticity
Grade 5 titanium is often used in subsea oil, offshore, gas applications, and is a general staple in the oil industry. The fact that it is corrosion resistant makes it the go-to in the marine world. Knowing that the harshness of the sea water will not have any sort of effect on the quality of the material makes it number one.
The medical field is another huge benefactor of this specific type of titanium, which is why “biocompatible” is a part of its many amazing factors. It has an innate ability to join with the human bone, which is called: osseointegration. This is the unique and fascinating way that the human body actually bonds with an artificial implant.
Doctors are able to help patients who are in need of a variety of things, such as:
- Spinal fusion cages
- Maxio-facial prosthetics
- Bone plates
- Expandable rib cages
- Finger and toe replacement
It is also non-toxic and will fight corrosion from bodily fluids, so not even the great mystery of moving parts inside the human body can take down this metal.
The long-term benefits that it has in the medical field is that it is non-ferromagnetic, which means that a patient who has this alloy in their body can be safely examined with MRIs and NMRIs.
But the glory of this top-notch version of titanium doesn’t stop there. Hospitals and doctors use a great number of surgical devices that are forged from grade 5 titanium, which can be found in hospitals (saving lives) all over the world:
- Needle and micro needle holders
- Suture instruments
- Vena cava clamps
- Lasik eye surgery equipment
- Dental scalers
- Dental elevators
- Dental drills
- Laser electrodes
- Surgical forceps
- Surgical tweezers
Dental implants are another way that titanium is leaving its mark on this world. By fusing titanium screws to the jawbone dentists can replace a missing tooth or even perform a full reconstruction that will be strong, natural, and last a lifetime thanks to its unyielding strength.
The sky’s the limit for the many-wonderful uses that grade 5 titanium will bring to our lives. The amount that we are currently using it in our day to day functions is astronomical and will only continue to grow. The bottom line is that this specific alloy was, is, and will continue to be an incredible asset in the past, present, and the future way of how we live our lives.
