Strongest compressive strength material

Click For Summary

Discussion Overview

The discussion centers around identifying the material with the highest compressive strength ever measured, specifically focusing on materials that exhibit gigapascal-level compressive strengths. Participants explore both man-made and natural materials, seeking clarification on the criteria for measurement.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Wally inquires about the highest compressive strength measured in any material, particularly looking for gigapascal-level strengths.
  • Some participants suggest that neutronium would have the highest compressive strength if calculated rather than measured, but clarify that Wally is interested in man-made materials.
  • There is a suggestion that diamond may have the highest measured compressive strength (>110 GPa), while aluminum oxide (alumina) is noted for its cost-effectiveness and decent compressive strength.
  • One participant expresses uncertainty about their ability to provide an answer and suggests waiting for a structural engineer to contribute.

Areas of Agreement / Disagreement

Participants generally agree on the interest in compressive strength measurements but have not reached a consensus on specific materials or values. Multiple viewpoints regarding the strongest materials remain, and the discussion is unresolved.

Contextual Notes

Participants have not defined the parameters for "measured" versus "calculated" compressive strengths, which may affect the discussion. There is also a lack of clarity on the specific conditions under which compressive strengths are measured.

Hi guys,

Would like to know what's the highest compressive strength ever measured in any material, and what material that might be. Specifically wondering if there are any materials with gigapascal-level compressive strengths. Thanks!

Rgds,
Wally

Do you mean actually physically measured as opposed to calculated? If not, neutronium would pretty much take the prize.

Oops, guess I should have clarified: I'm looking for man-made materials, so neutronium doesn't count (for now...).

Of course, if there are any natural materials that are stronger but that we've actually physically measured those work as well.
 
Got it. I can't help. A structural engineer will know. Hang on for a while and one will show up.
 
I would think it would be some sort of ceramic material. From the small amount of material specs I've looked at, I think diamond is the highest compression allowable I've seen (>110 GPa), but in a more cost-effective setting aluminum oxide (alumina) has a decently high compression allowable.
