What Is The Nitinol Alloy?
Nitinol, also called NiTi shape memory alloy, is a metal alloy composed of nickel and titanium, typically in a near 1:1 ratio. It has a unique shape-memory effect and superelasticity, allowing it to return to a preset shape when heated or recover its original form after significant deformation. It offers an expansion rate of over 20%, a fatigue life of 107 cycles, damping properties ten times greater than regular springs, and superior corrosion resistance compared to stainless steel. Due to its excellent biocompatibility, corrosion resistance, and mechanical properties, Nitinol alloy is widely used in medical devices (e.g., stents and orthodontic wires), aerospace, industrial manufacturing, and consumer products.
Nitinol-Rohr
Nitinol Tube is known for its unique shape memory effect and superelasticity. At room temperature, the Nitinol tube can undergo significant deformation and fully recover its original shape, while heating it to a specific temperature triggers its ability to “remember” and return to a pre-set form. It also has excellent biocompatibility, corrosion resistance, and high fatigue life, making it widely applied in medical, aerospace, automotive, electronics, and energy industries. Its high damping performance and temperature sensitivity further expand its potential in vibration damping, temperature control, and smart structures. HM can offer customized solutions for diameter and surface state according to specific requirements.

Nitinol Tube Advantages
- Smooth product surface
- High dimensional accuracy
- Good plasticity
- Cold working deformation of up to 40% or more
- Excellent superelasticity after treatment
Nitinol Tube Surface Finish
- Schwarz: Die Oberfläche ist “wie gesenkgeschmiedet” oder “wie gezogen”, wobei eine Schicht aus Bearbeitungsschmierstoffen und Oxiden zurückbleibt.
- Gereinigt: Die Oberfläche wird chemisch gereinigt, um alle Schmiermittel und Oxide zu entfernen.
- Boden: Die Oberfläche ist spitzenlos, um alle Beschichtungen zu entfernen und eine präzise Maßkontrolle zu erreichen.
Nitinol Tube Applications
- Medizinischer Bereich: Nitinol tubes are often used as medical devices such as vascular stents, guide wires, or catheters due to their super elasticity.
- Luft- und Raumfahrt: The shape memory effect of Nitinol tubes can be used to manufacture variable structural components in spacecraft, such as drive units or pipe connections.
- Industry and Engineering: Nitinol tubes can make temperature-sensitive valves or actuators due to their shape memory effect. Their superelastic properties make them suitable for vibration damping or shock absorbing equipment.
- Robotics & Automation: In micro-robots or bionic devices, Nitinol tubes can be used as muscle simulators to provide precise motion control.
Nitinol Tube Packaging
Nitinol Tube products are carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
