Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature 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.

About Pure Rhenium Pure rhenium is an important material for many scientific instrument filaments, as well as other electron and ion source filaments. Most rhenium naturally occurs in porphyry copper deposits. Hydrogen reduction is used to convert ammonium perrhenate to pure rhenium powder. The pure rhenium powder is pressed and sintered into ingots.
