· CoReB

CoReB is a cobalt-rhenium-boron intermetallic compound representing an advanced refractory alloy system designed for extreme-temperature structural applications. This material belongs to the family of high-entropy and transition-metal borides, developed primarily for aerospace and power-generation contexts where conventional superalloys reach their performance limits. Its appeal lies in potential weight savings and thermal stability compared to nickel-based superalloys, though it remains largely in the research and development phase for industrial deployment.

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.
