The Arms Race Between Gold Counterfeiters and Bullion Testers Is Heating Up
Fake gold bars are usually made of gold-plated tungsten because the density of tungsten, which is 19.25 times that of water, is very similar to gold’s density of 19.30. This makes tungsten the most suitable metal to create counterfeit gold bars whose dimensions and weight are very close to gold.
ECM testing machines have been very effective testing tools in detecting such tungsten bars because tungsten has a much lower conductivity compared to gold (18.52 vs 44.7 MS/m). Thus, as ECM testing machines have become more mainstream, it became easy to detect gold-plated tungsten bars.
