TaBeFe4
metal· JVASP-65143· TaBeFe4
TaBeFe₄ is an intermetallic compound combining tantalum, beryllium, and iron, belonging to the refractory metal alloy family. This material is primarily of research and developmental interest rather than established in high-volume production, with potential applications in extreme-temperature structural components where conventional superalloys reach their limits. The tantalum-beryllium-iron system is being explored for aerospace and advanced defense applications where materials must maintain strength and stiffness at elevated temperatures while minimizing weight.

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.
