The precise curve was constructed for cold pressure dependence on dencity for copper. It is in a good agreement with theoretical data of the Thomas-Fermi model with quantum and exchange corrections when compressions exeed 60-fold, and with static and shock-wave experiments when compressions are less than 2.4. Accuracy of this curve is estimated as 1–2% in pressure at given density in the whole region $0. Comparison with all previously known curves shows that their maximum errors are from 8% up to 25% for different authors. Our curve is about 10 times more accurate, so it can be the standard.
