This could be a revolution in bike locks. Right now compact battery powered cutting tools can remove just about any bike lock quickly and can easily be concealed.

Now that is pretty interesting. It seems they tuned the material to resist the angle grinder, drill and water jet but it would be interesting to see its ballistic resistance.

Wonder what a blow torch or other commonly available chemical agents would do to it.

I wish there were a way to get a sample of this to the lockpickinglawyer.

Will this work as armor?

I believe that answer hinges on whether "cut proof" is the same as "puncture-proof".

Physical shields for spacecraft?

Bullet proof vests?

Ammunition?

Combined with an energy dissipating foam it would make for some interesting ballistic armor. Especially at 15% the density of steel.

This is an absolutely amazing innovation, but bike thieves have already progressed to using powder-actuated pistons in order to break the internal mechanism of a lock. Much faster and easier than cutting anything.

So how do you shape/use it during manufacturing?

In Star Trek, they called it transparent aluminium!

I was thinking of the Hydraulic Press Channel...

It's odd that the title says "non-cuttable" and the tests they carried out in the article are all attacking it from one side, when most people will think of something like scissors that exert a high compressive force to shear the material.

To me, this material sounds more like it's highly abrasion-resistant than "non-cuttable".
