The hardest material that isn''t brittle? | Physics Forums

2011/3/25· I mean brittle in the scientific sense, but also that the material doesn''t easily fracture, which is the more colloquial, non-scientific sense of "brittle". So, I''m looking for the hardest (most difficult to pierce/cut) material that also is either not brittle at all, or if it is, requires loads of force to flex enough for the brittle failure to occur.

Silicon Carbide: The Return of an Old Friend | Sigma-Aldrich

Silicon carbide is harder, yet more brittle, than other abrasives such as aluminum oxide (Prod. Nos. 202606, 342750). Because the grains fracture readily and maintain a sharp cutting action, silicon carbide abrasives are usually used for grinding hard, low tensile-strength materials such as chilled iron, marble, and granite, and materials that need sharp cutting action such as fiber, rubber
