· JVASP-151434· TbAl4

TbAl4 is an intermetallic compound composed of terbium and aluminum, belonging to the rare-earth–transition metal intermetallic family. This material is primarily of research and development interest rather than established in high-volume industrial production, investigated for its potential in high-temperature applications and magnetic applications given terbium's strong magnetic properties. Engineers considering TbAl4 would typically be exploring advanced functional materials where rare-earth–aluminum combinations offer thermal stability, magnetic response, or specialized wear characteristics not easily achieved in conventional alloys.

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.
