Strongest compressive strength material

Click For Summary
SUMMARY

The highest compressive strength measured in man-made materials is attributed to diamond, which exhibits a compressive strength greater than 110 GPa. Aluminum oxide (alumina) is noted as a cost-effective alternative with significant compressive strength. The discussion clarifies that neutronium, while theoretically strong, is not considered due to its non-man-made nature. Participants emphasize the importance of physical measurements over theoretical calculations in determining material strength.

PREREQUISITES
  • Understanding of compressive strength and its measurement.
  • Familiarity with materials science, particularly ceramics.
  • Knowledge of diamond and aluminum oxide properties.
  • Basic concepts of material engineering and structural applications.
NEXT STEPS
  • Research the compressive strength of diamond and its applications in engineering.
  • Explore the properties and uses of aluminum oxide in various industries.
  • Investigate advanced ceramics and their performance metrics.
  • Study the methods for measuring compressive strength in materials testing.
USEFUL FOR

Materials scientists, structural engineers, and anyone involved in the development or application of high-strength materials will benefit from this discussion.

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.
