Rhenium | Re PubChem

Rhenium resembles manganese chemically and is obtained as a byproduct of molybdenum and copper refinement. Rhenium shows in its compounds a wide variety of oxidation states ranging from 1 to +7. Rhenium diboride (ReB2) is a hard compound having the hardness similar to that of tungsten carbide, silicon carbide, titanium diboride or zirconium ...

Rhenium Wikipedia

Rhenium improves the properties of tungsten. Tungstenrhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The hightemperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten alloys are produced with up to 27% of Re, which is the solubility limit.
