Iron Man-inspired material made from DNA and glass is 5x stronger than steel — and 4x lighter::Regular glass is brittle and fragile. But pure glass coated on DNA is a different beast entirely.

    “Stronger than steel”

    Recovering machinist here, and I agree. The other thing that annoys me about “StRoNgEr ThAn StEeL” is that there is a wide variety of different types of steel, all with different strength charachteristics. Some types of steel are 5x stronger than other types of steel.

    Same thing for Ford’s “Military grade” aluminum. The truck bodies are made out of 5052 and 6061 depending on how it’s shaped. Those are literally the most common grades of aluminum. And that’s what you’d make a truck body out of, but its funny.

      Also, industrial grade, surgical grade, space grade or whatever grade stuff is just funny marketing BS to me. You could probably come up with fancy terms for selling something as mundane as pencils. Instead of calling the materials wood and graphite, these marketing monkeys would probably use some fancy super high tech words instead.

        These advanced pencils are designed by A.I. and use biological carbon foam encasing stacked layers of graphene!

          How about throwing in some ”organic lignin composite nanomaterial” to jazz up the sales pitch. Just imagine the 300 million years of continuous development to form this fine material with extraordinary tensile properties…

        The only one I have personal experience with that’s real would be “analytical grade” with respect to chemicals. And probably Food grade. Those actually mean something.
