SUMMARY

The discussion centers on the search for manmade materials that are both extremely dense and cost-effective, specifically targeting materials with a density of 25 g/cm³ or less and a price under $1/g. Participants highlight that while osmium is the densest natural material at 22.59 g/cm³ and $100/g, tungsten emerges as a viable alternative, boasting a density of 19.6 g/cm³ and a cost of only a few cents per gram. However, the hardness of tungsten presents challenges in processing. The conversation emphasizes the need for clarity on the required size and shape of the material.

PREREQUISITES
  • Understanding of material density and its measurement (g/cm³)
  • Familiarity with the properties and applications of tungsten
  • Knowledge of material processing techniques, particularly for hard materials
  • Basic economic principles related to material costs
NEXT STEPS
  • Research the properties and applications of tungsten in various industries
  • Explore alternative dense materials such as depleted uranium or bismuth
  • Investigate techniques for machining and working with hard materials
  • Analyze market trends for bulk purchasing of dense materials
USEFUL FOR

Material scientists, engineers, and procurement specialists seeking cost-effective dense materials for industrial applications will benefit from this discussion.

Hi PF,
As you all may know, the densest naturally occurring material is Osmium, which is 22.59 g/cm3...but it also costs $100/g.

Is there any manmade dense material that is 25 g/cm3 and under $1/g? I know lead is the "dense" material to buy in bulk, but even that is only 11 g/cm3.

Any help would be great :D

I don't think so.

Tungsten is 19.6g/cm3 and only a few cents per gram raw. Finished parts can vary but under a dollar per gram is possible. It is rather difficult to work with due to its hardness.

What size and shape do you need?
