## Overview

This 2-way Nitinol shape memory alloy spring automatically expands at 60°C and contracts at 30°C, delivering reliable force in both directions. With a precise 0.7mm wire gauge and 9mm diameter, it offers lightweight, compact performance perfect for advanced mechanical and robotic applications.

## Description

Nitinol pre-trained 2-way memory helical/coil spring expands and exerts force when heated to 60C. Once cooled to room temperature, the spring contracts on its own with substantial pulling force. The spring contracts completely at room temperature by itself. Force is exerted in both directions entropy.

## Features

- Spring expands by itself when dropped in hot water, exerting force.
- Spring shuts closed by itself cooled to room temperature or dropped in cool water, exerting force.
- Spring wire gauge: 0.7 mm. Spring Diameter: 9 mm
- Fully contracted (cold) length: 15+ mm. Fully extended (hot) length: 40+ mm. Actual spring length may vary ±5 mm.
- Weight: 1.28 grams. Package contains One Spring.
