Rhenium is a refractory metal used in aerospace applications. Melting point: 3,186 °C. Tensile strength: 1,070 MPa.
ABOUT RHENIUM
Rhenium is one of the rarest metals on Earth with an extraordinarily high melting point of 3186°C and excellent high-temperature creep resistance. It is used as an alloying element in single-crystal turbine blade superalloys and as a coating for rocket nozzle throats. Iridium-rhenium alloys are used in satellite thrusters.
