· Be3 Fe1

Be₃Fe₁ is an intermetallic compound combining beryllium and iron in a 3:1 ratio, belonging to the class of lightweight metallic intermetallics. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in aerospace and high-temperature structural applications where the low density of beryllium combined with iron's strength could offer weight savings. The compound represents an exploratory effort to leverage beryllium's exceptional strength-to-weight ratio in engineered alloy systems, though practical adoption faces challenges related to beryllium's toxicity in processing and the brittleness characteristic of many beryllium-based intermetallics.

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.
