· JVASP-37732· Tm3Al2

Tm3Al2 is an intermetallic compound composed of thulium and aluminum, belonging to the rare-earth metal intermetallics family. This material is primarily of research and developmental interest rather than established in high-volume industrial production; it is studied for potential applications requiring the unique combination of rare-earth properties (high melting point, magnetic characteristics) with aluminum's lightweight attributes. The intermetallic class offers potential advantages in high-temperature structural applications and specialty magnetic devices, though Tm3Al2 specifically remains an emerging material with limited commercial deployment compared to more mature rare-earth 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.
