- • **Pre-Trained Reliability:** Ready-to-use shape memory alloy spring with predictable, repeatable actuation cycles.

## Overview

This 2-way Nitinol shape memory alloy spring (0.7mm wire gauge, 9mm diameter) expands at 60°C and contracts at 30°C, delivering force in both directions. Lightweight and compact, it offers reliable, pre-trained actuation ideal for innovative hardware applications requiring responsive thermal actuation.

## Description

Pre trained nitinol bidirectional memory coil expands and exerts force when heated to 60°C. Once cooled to room temperature, the spring contracts itself with substantial tensile force. The spring completely contracts at room temperature alone. Force is exerted in both entropy directions.

## Features

- Spring expands itself when placed in hot water, exerting force.
- The spring closes on its own when cooled to room temperature or dipped in cold water, exerting force.
- Spring wire gauge: 0.7mm. Spring Diameter: 9mm
- Full contracted length (cold): 15+ mm. Fully extended length (warm): 40+ mm. Actual spring length may vary ±5mm.
- Weight: 1.5 g. Package contains one spring.
