· JVASP-11984· CoRe3

CoRe3 is a cobalt-rhenium intermetallic compound representing a high-density refractory metal alloy system. This material combines cobalt's ferromagnetic and corrosion-resistant properties with rhenium's exceptional high-temperature strength and refractory characteristics, making it candidates for extreme service environments. CoRe3 is primarily of research and development interest for aerospace, power generation, and high-temperature structural applications where conventional superalloys reach their limits, though industrial adoption remains limited compared to established nickel-based or single-element refractory alternatives.

Export Control

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.
