· TmAu3

TmAu₃ is an intermetallic compound composed of thulium and gold, belonging to the rare-earth–noble-metal intermetallic family. This material is primarily of research interest rather than established in mainstream engineering applications, studied for its potential electronic, magnetic, and thermal properties that could be relevant to advanced functional materials development. The thulium-gold system is explored in materials science for understanding rare-earth intermetallic behavior and potential applications in specialized electronics or high-performance alloy systems.

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.
