## Overview

The Nitinol Shape Memory Heat Activated Wire is a 0.5mm diameter wire that transitions at 40ºC (104ºF), designed for innovative applications. Its unique properties allow it to return to a pre-trained shape when heated, making it ideal for creative projects that require precision and durability.

## Description

This wire will become rigid and return to straight when exposed to temperatures above 40ºC (barely hot water, lighter, heat gun, etc). Yes - it comes pre-trained STRAIGHT from the factory which is how you want it. You can re-train it if you want by heating it to elevated temperatures (150-250ºC) in the new desired shape. The wire has a lustrous titanium color (dark grey) with a bluish oxide tint on its surface. When freshly cut, the inner core is nickel white. Nitinol is very abrasion resistant and has self-healing properties, so the wire is quite hard to cut and kink. It feels very smooth and shiny to the touch. It does not require any special handling or protections from oxidation or moisture, and is non-toxic. Do not over heat it, as that will damage the property. If you are using electricity instead of hot water to activate it be sure to use a current limiting circuit. Sold by the foot; quantity of 1 corresponds to 12 inches or 31 cm.

## Questions & Answers

**Q: Good day. Just to confirm, the quantity that is ordered would be cut to the total length? (and not 12 in long pieces equal to the quantity selected)**
A: Yes, qty 12 = 12 feet, Not cut

**Q: what is pre-trained mean? is it still soft and bendable?  do you have smaller size (0.2, 0.3, 0.4mm)?**
A: We have 0.3mm in stock. You need to figure out if you need shape memory or superelastic wire, if shape memory, then what activation temperature. If you don't understand what I'm talking about then you can call or message us for help.

**Q: At what temperature can I retrain it to a different shape?**
A: 475-500°C for 45 minutes, ideally in argon or vacuum, then quench in water.
