## Overview

This 2-Way Nitinol Shape Memory Alloy Spring is a precision-engineered coil that expands when heated to 60°C and contracts when cooled to 30°C, exerting force in both directions. With a 0.7mm wire gauge and 9mm diameter, it offers reliable, repeatable shape memory action in a compact 1.28-gram form factor, ideal for educational, prototyping, or mechanical 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.

Review: Works - Cool for showing off.
Review: Kinda novel, but doesn't really keep it's shape - After deforming only a few times, when put in hot water, it only goes mostly back to original shape...

## 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.
