ultrahard
Beyond diamond's hardness
Ultrahard describes materials of extreme hardness, approaching or rivaling diamond: ultrahard coatings for industrial cutting tools, ultrahard carbon compounds.
The term appears mainly in materials science and engineering contexts.
More loosely, ultrahard can intensify any sense of hard: an ultrahard workout, ultrahard difficulty settings in video games.
