I thought Dragonforce was the hardest metal known to man?

Hardness isn’t the best thing to have in armor. In fact, extreme hardness means extreme brittleness.

Tensile strength is more desirable in armor. That’s the sort of strength that a string or rope, or Kevlar will have.

Those can stretch a bit before breaking.

Kevlar will stretch a bit when catching a bullet, this does a few things, but importantly it slows the bullet before stopping it.

So this new material will likely show extreme tensile strength rather than hardness.
