BeVFe
metal· JVASP-67619· BeVFe
BeVFe is an experimental beryllium-vanadium-iron intermetallic compound that combines the lightweight and high-stiffness characteristics of beryllium with vanadium and iron reinforcement. This research-phase material is being investigated for applications requiring exceptional strength-to-weight ratios and elevated-temperature stability, particularly in aerospace and defense contexts where conventional alloys reach performance limits. The addition of vanadium and iron to beryllium aims to improve machinability, reduce brittleness, and enhance fracture toughness compared to pure beryllium, while maintaining the low density advantages critical for weight-sensitive structures.

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.
