Nitinol Materials
We specialize in a fully integrated Nitinol supply chain. We’re the best providers of your Nitinol supply line—from wire and precision tubing to parts. Othala Technology is the industry’s dominant market for medical Nitinol. We’re consistently expanding the tapestry of materials science intelligence for MedTech Innovation.
We produce and ship directly, offering both stock items and custom designs. In addition, we provide a wide range of material options, with tolerances as tight as 0.005mm.
Nitinol’s distinctive properties offer several advantages in medical device manufacturing:
1.Shape Memory: Nitinol is an alloy that reverts to its original shape after a deformation. So, this makes it ideal for uses such as the stents and other devices that have to expand and compress in the body.
2.Superelasticity: It can be strained a good deal and retain its original shape. So, the chance of it becoming distorted or set is minimized.
3.Biocompatibility: Nitinol is a very resistant material against corrosion. Besides this, it is biocompatible so it is ideal for long-term implantation.
4.Fatigue Resistance: Nitinol also guarantees that devices constructed from this material can be used severally without developing faults.

Manufacturing Process of Nitinol Tubes
At Othala Technology, we focus on manufacturing Nitinol tubes to medical industry standards with a tolerance value of 0. 01mm. Our manufacturing process caters to the door-edge requirements of your medical device applications. So, we offer the industry’s best parts for your use. Here is the step-by-step process we follow to manufacture high-quality Nitinol Tubes;
1. Material Selection and Alloying
We chose high-grade raw materials, i.e. Nitinol alloys, to produce alloys accurately with the required composition. This facilitates the creation of the desired ratio of nickel/titanium that gives the material a good shape memory and makes it a superelastic material.
2. Melting and Casting
We employ the most advanced methods to make the Nitinol ingot, i.e. controlled casting process. It is used to guarantee uniformity, and this makes the production process produce tubes that are of high quality.
3. Hot and Cold Working
The Nitinol ingot is then exposed to several hot and cold working processes including forging rolling or drawing. This minimizes the material to the required tubular size. At the same time, it improves the mechanical properties of the material.
4. Precision Tube Drawing
Precision Tube Drawing is the accurate last stage. Here the Nitinol tubes are graduated to the final size. Our tubes are thin because we use special dies and mandrels to pull the tubes down to the required specifications of thickness or diameter.
5. Care and Treatment of Heat and Shape
We use controlled heat treatments to induce the shape memory effect. So, it can enhance the superelastic properties of the Nitinol tubes. This step is critical in medical applications because it improves performance and is reliable and consistent.
6. Surface Treatment and Finishing
At this stage, we use state-of-the-art surface treatments to ensure that our Nitinol tubes have improved biocompatibility and better corrosion resistance. Passivation and other fine operations help us to get a flat and shiny surface free of any contaminants. So, they can effectively be used in the medical field.
7. Quality Control and Testing
We have instituted strict quality check mechanisms throughout the production line for quality production. Besides this, our adequate dimensional inspections, mechanical tests, and surface analysis ensure that the Nitinol tubes meet the highest dimensions of accuracy and quality.
These selected characteristics, particularly shape memory, superelasticity, and biocompatibility make Nitinol tubes highly valuable in the medical industry. These properties make Nitinol important in many medical uses and provide a unique solution to many of the patient’s medical needs. Besides improving the working of some of the medical equipment. Below are the vast applications of Nitinol tubes in the medical industry:
- Coronary, Peripheral, Neurovascular Stents: Nitinol has flexibility and the ability to expand. So, it is well-suited for preserving blood circulation and strengthening vessels.
- Vascular, Coronary, and Peripheral Guidewires: They provide great strength and flexibility to enable the surgeon to be precise in the least invasive procedures.
- Angioplasty, Electrophysiology, Diagnostic Catheters: It guarantees that the introducers can be steered to the difficult-to-access areas and are also reliable.
- Orthodontic Devices like Archwires and Braces: This material applies equal pressure and optimizes dental correction among others.
- Surgical Instruments like Retrieval Devices, Scissors, and Forceps: Nitinol gives accuracy and strength to minimally invasive devices and instruments.
- Endoscopic Devices like Biliary, Gastrointestinal, and Urological Stents: L Nitinol stents have flexibility and effectiveness in the long term in the different systems in the body.
- Implantable Devices like Bone Anchors and aneurysm Clips: Nitinol possesses shape memory qualities. So, it contemplates providing long-term secure, and stable implants.
