2-Way Nitinol Springs with Shape Memory Alloy (Af 60°C / Mf 30°C)
Unlock Smart Motion with Nitinol Springs
See how Nitinol springs work—made from a smart alloy that changes shape and remembers it based on heat.When heated above 60°C (Af), the spring transforms into its programmed shape. Cool it below 30°C (Mf), and it reverts to a different shape. This unique two-way memory effect repeats with every thermal cycle, delivering consistent and automatic actuation without motors or power sources.
Built with Premium Superelastic Nitinol
We manufacture our 2-way Nitinol springs using only high-quality Nitinol, including advanced superelastic gradesCapable of withstanding extensive bending, superelastic Nitinol instantly reverts to its initial form with no residual distortion.These springs perform reliably under high-stress applications, offering exceptional fatigue resistance and long-term durability. You get smooth, repeatable movement across millions of cycles.
Find the Ideal Size for Your Application
We provide Nitinol springs in a wide range of wire diameters and coil configurations. Whether you need ultra-thin springs for delicate mechanisms or robust sizes for heavy-duty tasks, we can tailor a solution to your needs. Let us help you select the perfect spring for your system—precision is always our priority.
Key Applications for 2-Way Nitinol Springs
Our shape memory springs excel in many fields:
-
Medical Devices: Enable actuation in miniature tools, surgical arms, and temperature-sensitive valves.
-
Aerospace Components: Automatically adjust control surfaces or vents in response to ambient temperature.
-
Automotive Safety Systems: Trigger heat-sensitive sensors, actuate release systems, or protect components.
-
Smart Home Technology: Automate vent control, faucet flow, and climate-responsive functions.
-
Precision Robotics: Generate smooth, human-like movements in robotic limbs or grippers.
-
Safety Release Mechanisms: Act as thermal cutoffs to disconnect components safely in overheating situations.
How Shape Memory Alloy Technology Works
Nitinol is a smart metal known as a Shape Memory Alloy (SMA). Its magic lies in its ability to switch between two crystal structures:
-
Martensite (Cool Phase): Below 30°C (Mf), the alloy is soft and flexible—ideal for shaping.
-
Austenite (Hot Phase): Above 60°C (Af), it becomes rigid and snaps back to its “remembered” shape.
We expertly train each spring to exhibit two-way memory—meaning it transitions between two distinct forms depending on temperature alone.
