Tungsten and rhenium are the two most difficult pure metals to melt, and they become even more difficult to melt when combined. A bar of tungsten-rhenium would be harder than many tempered steels and less conductive than gold, which will cause it to fail almost every other type of test, most of which are much more likely than a density test.
