Density of materials: metals, polymers and ceramics compared
properties/density-of-materialsDensity of metals, polymers, ceramics and composites ranked from sourced values, with stiffness and thermal conductivity alongside. Ranked by the column you pick. Measured values come first; calculated values are labeled, and predictions are never mixed in as measurements.

Severity is the editors' reading of the cited sources, not a safety certification. "none listed" means no sourced failure risk has been entered, which is not the same as safe.
How to read this
- Measured values come from a test or a flight. Calculated values are worked out from the material's formula. Prediction values come from a model.
- no data means nobody has published a value we could source. It does not mean zero.
- Material values describe the active material. Cell values describe a finished cell, which varies by manufacturer. Check the conditions before comparing cell values.
- Every value links to its source, with the place in the source where it can be found.
The measurements
| Measurement | Better when | How it is tested |
|---|---|---|
| DensityMass per volume, which sets volumetric energy | depends on the use | Crystallographic or tap density |
| Young's modulus | depends on the use | |
| Thermal conductivityHow well it moves heat | depends on the use | ASTM E1461 |
