## Overview

This Nitinol memory metal spring is a high-precision shape memory alloy that contracts automatically when heated above 45°C (113°F), delivering up to 2.5N of force. With 21 coils and a 0.75mm wire diameter, it offers durable, repeatable performance ideal for innovative projects, educational demos, and precision applications.

## Description

Nitinol memory spring can be stretched at room temperature or below, and upon heating to 45C or above (113 F+) it spontaneously contracts to its original form, exerting force. This small spring can provide up to 250 grams of pulling force without risking permanent deformation to the spring (operation within 150 grams of tension is recommended for longevity).

Review: As expected - As expected.
Review: Just what we needed! - We used this for a object lesson in our kids ministry. Worked great, although a little small, only about an inch long but when stretched out and then heated, the effect is great!
