· JVASP-64960· BeFe4Re

BeFe4Re is an experimental intermetallic compound combining beryllium, iron, and rhenium. This material belongs to the rare-earth-containing refractory metal family, which is primarily investigated in research contexts for extreme-temperature and high-performance applications. The addition of rhenium to iron-beryllium systems typically aims to enhance creep resistance and thermal stability, making it of interest for aerospace propulsion and advanced energy systems where conventional superalloys reach 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.
