· JVASP-73699· TaBeFe

TaBeFe is a tantalum-beryllium-iron ternary alloy belonging to the refractory metal family, combining the high-temperature stability of tantalum with additions of beryllium and iron to modify mechanical and physical properties. This composition appears to be a research or specialized alloy rather than a widely commercialized material; such ternary systems are explored for applications requiring extreme hardness, high stiffness, and density control in demanding environments. Engineers would consider this material where conventional refractory alloys fall short on cost or weight, or where the specific elastic and strength characteristics of this composition offer advantages over binary tantalum alloys or tungsten-based alternatives.

Export Control

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.
