Rhenium is very expensive; for example a rhenium foil (25 mm x 25 mm, 0,025 mm thick, 99,97 % purity) the price is approx. 150 US . Rhenium foils are largely used in mass spectrometry.
Refractory Metals and their alloys are a special class of materials with exceptionally high melting points and resistance to corrosion, wear and abrasion, thermal shock, and creep deformation. In addition to their melting points (greater than 2200 °C), these metals exhibit excellent tensile strength, hardness, and densities, and are both electrically and heatconducting, making them ideal ...

Tungstenrhenium alloy xray tube. The conical disk in this sample is a heavy slab of tungstenrhenium alloy. The structure above holds a filament that releases electrons, which are accelerated with a high voltage to strike the tungstenrhenium disk, generating xrays when they strike.
About 3% Rhenium/97% Tungsten Wire The development of 3% rhenium/97% tungsten wire is a result of a continuous research effort that has been conducted since the early 1900''s. One of the first accomplishments of this research was a nonsag grade of tungsten wire, which used grain growth controlling additives to modify the recrystallized structure.

In relation to this question specifically, I simply searched for "rhenium" on MatWeb and browsed the single page of results. I was surprised to find that the increase in density that rhenium causes is so strong that the tungsten alloy with the lowest nominal rhenium content tungsten with 3% rhenium was significantly more dense than gold. Re ...
