Nitinol and Specialty Alloy Solutions


Nitinol and Specialty Alloy Solutions

Nitinol solutions are highly relevant in the manufacturing of medical devices due to their unique shape memory and super elasticity properties. As a nickel-titanium alloy, nitinol is highly corrosion-resistant and biocompatible, making it ideal for implants and medical tools. At our company, we offer specialized services in the manufacturing of medical components and devices using high-quality nitinol. From coronary stents to guide wires and dental files, our engineering experts are trained to design and manufacture custom products according to our client’s needs.

What is Nitinol and its properties?

This super elastic and versatile material is made of an alloy of metals Nickel and Titanium in almost equal parts and has been known as Nitinol since 1961. This alloy’s memory properties are unique and highly evaluated after shape deformations. Nitinol’s ability to recover its original shape after heat applications make it ideal for medical instruments. It brings the possibility of making resources to widen arteries, compress fractured bones and adapt dental guides. The best part is that the application and delivery of the components is easier because it expands with temperature change once placed accordingly. Nitinol is non-toxic and corrosion resistant, so it is perfect for the creation of MedTech tools. Furthermore, flexibility and elasticity allow the elaboration of instruments for interventions that require meddling with minimal invasion and permanent implants with excellent durability.

Applications of Nitinol

Nitinol alloy represents a revolution among the different metals thanks to its excellent characteristics. Due to this, its applications are varied in overly complex industries, and let us see some relevant uses.

Use of Nitinol in the Medical Industry

Nitinol’s bending and transformation ability, especially in low-temperature environments, makes this metal a perfect component for medical tools and elements. An advantage of super elastic Nitinol in the medical industry for tools manufacture:
  • Guide wires for clinical purposes, such as flexible endoscopic devices, make them less invasive in the body, especially in narrow areas. It can also take a rigid form when it is required.
  • Tubes, such as catheters, filters, or needles. Thanks to this material, they are flexible, bio-compatible, versatile, and minimally intrusive.
  • Stent and implants delivered by catheters to expand vein and arteries resulting in unrestricting blood flow or holding material to replicate valves for cardiological applications.
  • Stone retrieval baskets for renal or biliary interventions. For these surgeries, it collaborates with a safe and practical intervention. The wireframe adjusts and grips to remove stones.
  • Dental files and arch wires in orthodontics and dental medicine that fit the tooth shape and apply the correct pressure for patient well-being and treatment effectiveness.
In recent years, it has been used in arterial disease treatment which has been widely studied and promoted. Therefore, today it is one of the most relevant Nitinol applications in the medical field. In addition, thanks to its biocompatibility, it is excellent for micro-pumps preparation, stents, or bypasses.

Nitinol Products

Nitinol is a versatile alloy metal that boasts excellent biological compatibility and anti-corrosiveness. Manufacturers utilize its unique properties to create a variety of products for different industries. The most sought-after Nitinol products include:

  • Stents: Nitinol’s super elasticity and shape-memory properties make it an ideal material for manufacturing coronary and peripheral artery stents.
  • Guidewires: Nitinol’s flexibility and kink resistance make it suitable for producing guidewires used in minimally invasive surgeries.
  • Orthopedic implants: Nitinol can be used to create bone plates, screws, and other implants that can withstand high stress loads and offer excellent biocompatibility.
  • Dental instruments: Nitinol’s shape-memory properties are utilized in orthodontic wires, arch wires, and endodontic files, making it an ideal material for dental instruments.
  • Neurovascular devices: Nitinol’s biocompatibility and radiopacity make it suitable for manufacturing aneurysm clips, embolization coils, and other neurovascular devices.

Manufacturers can also incorporate additional elements like chromium or cobalt into Nitinol components composed of titanium and nickel to enhance their super elastic properties. Nitinol is available in various forms such as tubes, sheets, strips, and wires, making it easier to manufacture components and parts based on the specific application and design.
