material that can’t be cut

So......it's obviously not cheese.

To paraphrase a career Marine I know, if you want to really test it, give it to three Marine Corps E-3 infantrymen assigned a punishment fire watch at 29 Palms, one that has them living in shelter halves in the middle of no where for the entire Independence Day holiday.

Give it to them Friday at 1830.

Come back to check on it every six hours.

If it remains uncut at 1900 on Friday, it's a miracle.

Obviously what was used to coat the Knight Industries Two Thousand (KITT) automobile . . . .

Engineers claim to have created the first manufactured material that can’t be cut..

Then they should make a saw blade out of it.

Can any liquid be cut?

They'll use it to make packaging material for small parts. That, and child-resistant medicine bottles.

If it can't be cut, can it be shattered?

But ... Will it blend !?

A simple shear will cut it easily, provided you have enough tonnage and are using tungsten carbide blades.

Just wait until a piece of it comes up in a divorce.

Shit will get halved quick.

A material that can't be cut reminds me of the Aggie joke about the chemistry class at A&M that invented a liquid that will eat through anything, but they didn't have anything they could put it in.

Let’s see - if I recall nothing on earth will withstand 7,000* F. A Plasma torch produces something in excess of 40,000* F.

Please correct my numbers if yours are more accurate. Mine are conservative.

HaHa...my neighbor says if you lock 3 Lance Corporals in a room and throw in a tricycle, 2 of them will need an emergency room visit within 15 minutes.

Laser or Plasma should cut it easily. Even a regular old Oxy Acetylene torch should work.

Can't use an angle grinder, drill, or high-pressure water jet. What about single point diamond cutting?

This press release sounds like something an inexperienced engineer would say or something a marketing guy would say. I graduated nearly 25 years ago and if there is one thing I've learned is that there isn't anything that is xxx-proof (e.g. idiot proof) and it's all merely resistant up to certain parameters.

My first job out of college I did custom design work, and the fabrication shop behind the office had 2 plasma tables. One of the plasma tables cut 2.5" steel in a single pass. I'd wager that plasma table wouldn't break a sweat on that. Especially, when you add in this little factoid:

quote:

The structure is then heated in a furnace to ca. 760 °C (depending on the melting range of the used aluminum alloy) for between 15 and 20 minutes. The titanium dihydride begins to decompose at approximately 470 °C, releasing hydrogen gas. The release of the high-pressure hydrogen expands the molten aluminum, creating voids.

I'd wager a large sum of money that if you preheat to 800C then there is a wide range of cutting implements that would work.
