Nitinol Cable Structures and Specifications

Nitinol cable uses a multi-strand structure and is available in configurations such as 1×3 and 1×7. The configuration can be matched to device space, flexibility requirements, and force-transmission needs.

1×3 Nitinol Cable

• 

  A compact structure stranded from three Nitinol wires. The 1×3 configuration uses fewer strands and offers relatively high flexibility, making it suitable for component designs with limited space that require flexible movement and precision control.

Key features:

• Compact stranded structure
• Relatively high flexibility
• Suitable for small precision components

1×7 Nitinol Cable

• 

  The 1×7 configuration combines more individual wires than the 1×3 structure and can provide better structural stability. It is suitable for applications requiring more stable force transmission and mechanical performance.

Key features:

• Multi-strand structure improves stability
• Better suited to force-transmission requirements
• Suitable for complex moving components

FAQ

1. What is Nitinol cable used for?

Nitinol cable is mainly used in medical device components requiring flexible movement, precision control, and stable force transmission, such as flexible connections, drive mechanisms, and precision moving components in endoscopic, orthopedic, and dental instruments.

2. What is the difference between 1×3 and 1×7 Nitinol cable?

A 1×3 Nitinol cable is stranded from three Nitinol wires, providing a more compact structure for applications with higher flexibility requirements. A 1×7 Nitinol cable consists of seven Nitinol wires and offers greater structural stability for components requiring more stable force transmission.

3. What is the difference between Nitinol cable and stainless steel cable?

Nitinol cable uses a multi-strand Nitinol structure to provide good flexibility and superelastic recovery. It is suitable for precision medical device components with demanding space, motion-control, and repeated-bending requirements. Stainless steel cable typically has greater stiffness and is more commonly used for general mechanical transmission and structural applications.
