· JVASP-133132· Re2W

Re₂W is an intermetallic compound combining rhenium and tungsten, two refractory metals known for extreme hardness and high-temperature stability. This material represents an emerging class of ultra-dense, high-strength intermetallics primarily investigated in research settings for applications demanding exceptional thermal resistance and structural integrity at extreme conditions. Industrial adoption remains limited, but the Re–W system is of particular interest for aerospace and nuclear applications where conventional superalloys approach their performance limits.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
