Custom Nitinol Shape Memory Alloy Wire with Copper Riveted Terminals

Used in smart wearables, consumer electronics, robotics, automotive electronics, unmanned systems and other compact electromechanical assemblies where repeatable movement and reliable electrical connection are required.

Manufacturing Process

Nitinol wire forming → in-mold riveting → pull-force test → dimensional inspection → resistance test

This process reduces secondary assembly steps and helps maintain consistent terminal position and joint quality in volume production.

Custom Manufacturing

Send us your 2D/3D drawing, wire diameter, overall dimensions, terminal material, resistance requirement and expected pull force. We can review the design for manufacturability and recommend a suitable forming and riveting process.

Nitinol / NiTi shape memory alloy wire
Copper terminal options
Critical dimension tolerance: ±0.03 mm
Riveted joint pull force: up to 3 kgf
Resistance: < 0.82 Ω
In-mold riveting for better part-to-part consistency
Pull-force, dimensional and resistance inspection available
Custom forming and assembly to customer drawings

Our custom Nitinol (NiTi) shape memory alloy wire assemblies are formed and riveted in-mold with copper terminals for a consistent mechanical and electrical connection.

We control critical dimensions to ±0.03 mm. After riveting, the joint can achieve a pull force of up to 3 kgf and electrical resistance below 0.82 Ω.

Each part can be made to your drawing, including wire diameter, formed shape, overall length, terminal design and riveting position.
