Benefits of Titanium in the Medical Industry

Leave a Comment

The medical industry has used titanium in surgical and dental equipment since the 1940s. Today, it 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.

Grades of Medical 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.

Positive Characteristics of Medical Titanium for Biomedical Implants

Titanium has many characteristics that make it the ideal metal for medical applications. Its advantages include:

  • Durability
    Medical implants made from titanium alloys routinely last 20 or more years inside the human body.
  • Higher strength-to-weight ratio
    Titanium is stronger and lighter than stainless steel, which largely accounts for its widespread use in surgical implants.
  • Non-ferromagnetic property
    Because it isn’t magnetic, medical titanium doesn’t interfere with magnetic resonance imaging (MRI) machines. Because of this property, patients with titanium implants can still safely undergo MRI examinations.
  • Biocompatibility
    Unlike other metals, medical titanium can remain in constant contact with living tissue without adversely affecting it.
  • Biointerfacing
    Titanium implants have an engineered biointerface with biomimetic motifs that increase cell contact area by as much as 75%, enhancing the cell’s binding properties. As a result, their use further reduces the chance of implant rejection.
  • Osseointegration
    Medical titanium implants can physically bond with natural bone, eliminating the need for adhesives.

Choosing the Right Sheet Metal for Your Manufactured Components

Leave a Comment

Choosing the right sheet metal for your manufactured components is crucial in ensuring that your parts will perform optimally. To make sure you choose the correct sheet metal, it is important to consider factors such as material, size, design, and tolerance requirements as well as manufacturing and fabrication processes that the material will undergo.


Material and Size

There are many metal and alloy options to choose from when selecting a sheet metal material. To ensure that you choose the appropriate material for your particular needs, it is important to ask the following questions:

  • What is the desired size of your component?
  • How strong does your component need to be?
  • Does the material need to be easy to work with in terms of weldability, ductility, tensile strength, and machinability?
  • What is the budget for your project?
  • Is your component going to be used in an application, such as automotive or aerospace, that requires an excellent strength-to-weight ratio?


Design and Tolerance

When choosing a sheet metal for your manufactured parts, it is necessary to consider design and tolerance requirements such as:

  • water jet cuttingWall thickness
  • Bend allowance
  • K-factor
  • Orientation of holes and slots


Manufacturing Processes Utilized

The sheet metal you choose needs to be capable of withstanding the manufacturing processes that your component may undergo before completion. Some common manufacturing processes include:

  • laser cuttingLaser cutting. Laser cutting is ideal for precision designs with tolerances up to +/-0.005″.
  • Waterjet cutting. Waterjet cutting uses a high-pressure jet of water containing abrasive particles to cut plates of metal up to 150mm thick.
  • Bending forms the metal by applying stress along an axis with the use of V-bend dies, goose-neck dies, U-bend dies, or others, depending on the sheet metal bending design considerations.
  • Machinists can form a hollow or curved surface by drawing the metal into a die using a mechanical punch.
  • Annealing involves heating the metal to a specific temperature for a fixed period then cooling slowly to change the microstructure. Annealing softens and improves the machinability of metal and provides enhanced electrical conductivity.


Fabrication Processes

Fabrication involves finishing corners and closing gaps to enhance or maintain the shape and integrity of the finished product. Techniques like welding, riveting, and brazing join the metal, although the process used will depend on the component’s material.

Common welding techniques include:

  • TIG welding. Tungsten inert gas, or TIG welding, does not use filler metal. Instead, it uses a tungsten electrode in an inert atmosphere of argon or helium to achieve a strong, high-quality, precise weld that is environmentally friendly.
  • MIG welding. Metal inert gas, or MIG welding, is a cost-effective, fast, and clean option when compared to TIG welding. However, it is less reliable and more hazardous than TIG welding.
  • Brazing is a joining method used for aluminum and brass components.

Knowing the differences between these processes is important as the one you choose will directly affect the final product as well as the cost.
