With a melting point of 3180 ºC, Rhenium has the second-highest melting point.. Only osmium, iridium, and platinum exceed its density of 21.04 g/cc. Because of its high melting point, rhenium is a refractory metal. Rhenium offers high electrical resistivity across a wide temperature range. Its high temperature strength gives it design flexibility. Products made from rhenium can be thermally cycled thousands of times with no ill effect. It can be alloyed with tungsten or molybdenum and, near the solubility limits, imparts improved ductility to those materials. High-temperature strength, low friction, ductility and other unique properties make it the material of choice for many critical applications.

A catalyst in the petroleum industry. Due to its high electrical resistance and low vapor pressure, rhenium is an excellent choice for filaments.Also used in medical applications. Radioactive rhenium is used in prevention and treatment of restenosis, which develops following balloon angioplasty. Rhenium is also highly effective in the treatment of liver tumor(s).
Rhenium is drawn into wire and rods. Wires made of rhenium are used in photoflash lamps in photography, high temperature thermocouples, and thermistors.
Rhenium in the form of pellets is added to nickel-based super-alloys in order to raise the operating temperature of turbine blades in aircraft and gas turbine engines.
Rhenium is also added to molybdenum and tungsten to improve their qualities especially ductility. These rhenium-alloyed materials find uses in mass spectrographs, light filaments, and ion gauges. Common alloys of rhenium and molybdenum are with 41-47.5% rhenium (Mo- 41Re, and Mo- 47.5Re). These Mo-Re alloys are mostly used in electronics, space, and nuclear industries. Alloys of rhenium and tungsten are with 3-5% and 25% W-3 Re, W-5Re, and W-25Re. W-Re alloys are mostly used in electronics as filaments and thermocouples.
