· JVASP-19824· TmAl3

TmAl3 is an intermetallic compound composed of thulium and aluminum, belonging to the rare-earth intermetallic family. This material is primarily of research and development interest rather than established in high-volume production, as intermetallics containing thulium are typically explored for specialized high-performance applications requiring the unique combination of rare-earth properties with aluminum's lightweight characteristics. Engineers consider TmAl3 mainly in advanced materials research contexts where its stiffness and density characteristics might enable novel applications in aerospace, electronics, or thermal management systems, though practical adoption remains limited compared to conventional aluminum alloys or more commercially developed intermetallics.

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.
