Re3W

Re3W is an intermetallic compound composed of rhenium and tungsten, belonging to the family of refractory metal intermetallics. This material is of primary interest in high-temperature applications where exceptional strength retention and oxidation resistance are critical, though it remains largely in the research and development phase rather than widespread commercial production. The rhenium-tungsten system is investigated for aerospace and energy applications where conventional superalloys reach their thermal limits, offering potential advantages in ultra-high-temperature environments despite challenges in manufacturability and cost.
