· JVASP-22762· TmAl7Au3

TmAl7Au3 is an intermetallic compound combining thulium, aluminum, and gold—a rare-earth metal alloy system that remains primarily in research and development rather than established industrial production. This material belongs to the family of rare-earth intermetallics, which are typically investigated for specialized high-temperature, magnetic, or electronic applications where conventional alloys fall short. The specific combination of thulium (a lanthanide), aluminum's light weight and thermal conductivity, and gold's chemical stability suggests potential applications in niche aerospace, thermoelectric, or advanced electronics contexts, though this particular composition is not yet a mainstream engineering material.

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.
