contact usEquivalent molar concentration per liter. Antimony weighs 6.684 gram per cubic centimeter or 6 684 kilogram per cubic meter, i.e. density of antimony is equal to 6 684 kg/m³; at 25°C (77°F or 298.15K) at standard atmospheric pressure .
contact us· Antimony is present only in very low concentration in native copper. 1,065 native copper specimens were examined through neutron activation analysis and show less than 0.01% antimony, with a maximum of 0.089% and a mean value of 4.4 ppm [100: p.23, table 2.2]. Thus, the antimony in native copper cannot result in a copper–antimony alloy.
