Nitinol Guide Pin: Precision Shape Memory Alloy for Critical Alignment
The Smart Advantage of Nitinol
Our premium nitinol guide pin delivers unmatched precision and reliability, engineered for demanding applications. Made from a nickel-titanium alloy known as Nitinol, it offers two extraordinary properties — superelasticity and the shape memory effect — making it ideal for high-precision industries.
Applications Across Industries
-
Medical Devices – Perfect for stents, surgical tools, and orthodontics thanks to excellent biocompatibility.
-
Guidewires & Catheters – Navigates delicate channels without kinking, maintaining shape memory.
-
Aerospace & Robotics – Provides precise motion in actuators and couplings, triggered by temperature changes.
-
Industrial & Consumer Goods – Adds fatigue resistance to eyeglass frames, safety releases, and connectors.
Nitinol Guide Pin vs. Guidewire
While guidewires are thin and highly flexible for navigation, the nitinol guide pin is rigid or semi-rigid, ensuring exact positioning and alignment during assembly or machining. Its dimensional stability, superelastic recovery, and kink resistance make it essential in precision manufacturing.
Manufacturing Excellence
-
Material Selection – High-purity nickel and titanium melted under strict conditions.
-
Forming – Drawing or machining to achieve precise diameters and lengths.
-
Heat Setting – Programming shape memory via controlled heating and quenching.
-
Surface Finishing – Polishing, etching, or coating for smooth operation and corrosion resistance.
-
Quality Testing – Verifying dimensions, mechanical strength, and memory performance.
Activation Process
Bend the guide pin at room temperature, heat it to its activation point (often near body temperature), and watch it return to its original form without external force.
