Mechanical engineer here. This article is very light on a lot of detail which would allow you to reasonably compare this material to steel, plastic or any other material. Just a few that come to mind: Hard materials are usually brittle materials that fail suddenly. How tough is it? ie. Can it accept some deformation without significant weakening and will it stretch or crack prior to failure? What is its compressive strength? What is it's tensile strength? Could it be used to reinforce concrete? Pipe liquids or gases? Does it's strength drop when it gets wet? How dense is it? How flammable is it? How easy is it to machine without damaging it? And of course the big one - how much does it cost?
