No materials match.
These values come from different cells and tests, so the order is a guide, not a verdict. Hover a value, or open the material, to see its conditions.

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.
- Every value links to its source, with the place in the source where it can be found.
