Density of Precious Metals & Their Alloys

Note:

Knowing the density of precious metals and thier alloys is a great tool in order to verify its authentic . just need to divide the wieght by the volum and compare the results with the theoretical number in the table.

Please consider that the data present in the table below, are theoretical, as casted material may not be 100%  compressed, and the density may be a little lower. 

Other point to consider is that the theortical density mesure at 20º c. As metals tends to expand when heated, the expected density to get down when temp is over 20°
