· JVASP-51115· CoReGe2

CoReGe2 is an intermetallic compound combining cobalt, rhenium, and germanium, representing an experimental high-performance material from the refractory intermetallic family. This compound is primarily of research interest for extreme-environment applications where conventional alloys reach their performance limits, with potential use in aerospace propulsion, high-temperature structural applications, and advanced electronics where the combination of metallic bonding and intermetallic ordering can provide superior strength retention and thermal stability compared to traditional superalloys or refractory metals.

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.
