Memory Wire (Nitinol) questions
Memory Wire (Nitinol) questions
(OP)
[copied from the Electrical Engineering Other Topics forum]
Here's a question about memory wire, also known as nitinol wire. I'm looking for something that is difficult to cut, and extremely flexible. I'm thinking that the nitinol wire meets my flexibility requirements, but I can't find a spec sheet that will tell me whether it will be easy to cut or not.
The application is a security strap that would be a rubber strap with a wire embedded inside. The goal is to prevent cutting with ordinary scissors while it's worn on a wrist or ankle. Flexibility is needed to allow it to wrap to different sizes, and high security is required to prevent removal.
I'd like to find something that meets these requirements and is smaller than 1/16" in dia. Am I asking too much?

might be a place to start. Steel spring wire is very strong and can be used very thin for your application.
If you want more flex you should look at low modulus alloys. Ti wire is very flexible and strong.

The links in my previous post will give you a lot on the specifications.
There is a lot that is proprietary concerning the alloy, particularly in the way that it is made. It is not an easy piece of metal to manufacture. And yes, it does some pretty amazing things.
