Proteus: The World's First Manufactured Non-Cuttable Material

The material, named Proteus, is only 15% the density of steel and can be used to make indestructible bike locks and lightweight armor.

Super tough material called Proteus. If you look at this image,



you can see what its made of, aluminum bars mixed with a foaming agent and ceramic. Heat it up, the foaming agent causes the aluminum to expand and everything gets jam-packed.

• A drill bit or angle grinder will cut through the outer layer of the Proteus plate.
• Once it reaches the embedded ceramic spheres, it begins to vibrate aggressively.
• These vibrations will dull the tool’s sharp edges.
• Then, fine particles of ceramic dust will start to fill up gaps in the matrix-like structure of the metal.
• These particles cause it to become harder the faster you drill or grind “due to interatomic forces between the ceramic grains,” and “the force and energy of the disc or the drill are turned back on itself, and it is weakened and destroyed by its own attack.”

Proteus’s potential goes beyond bike locks and lightweight armor. It can be used to make any kind of protective equipment that shields against people using cutting tools.

I have to wonder what the embedded ceramic does to the tensile strength though, i.e. does it bend or break when smacked with a hammer or subjected to bending forces? when in doubt a cutting torch should still work.

You could always cut through the bike and then weld that back together again.
