Some people has the idea that tungsten gold plated bar can be a substitute of gold bar as memento. This is an opinion which has stirred the discussion. The reason should be concluded to the properties of tungsten bar with gold plated.
In theory, the density of tungsten gold plated bar is 19.1g/cm3, which is approximately 70% denser than lead, uranium could be used as material of making fake coin. However, it is weakly radioactive and not as dense as gold, so it does not appear to be a practical method. Even so, it still has the value as souvenir to be remembered.
Tungsten gold plated bar is corrosion resistance. This can be the reason for this bar as memento to memo some important events. For example, engrave the marriage anniversary date, birthday, or Olympic day, or some important festival.
