John Stagge asked the Naked Scientists:
What is the best material to use for a bistable spring for it to last the longest?
You did a video on bistable springs and I am doing some research on this type of spring. We are using this spring for a cell phone case for a mount, a grip and a kickstand. We are using this but in testing we can only get about 7000 clicks out of it before the springs starts to crack or split. We are using a form of steel now like most tape measures with a lot of Manganese in it. Would using a form of stainless steel be a better material for this application?
What do you think?

We did a programme on bistable structures with the engineers at Cambridge University. This is the link:
