· ThAl3

ThAl3 is an intermetallic compound composed of thorium and aluminum, belonging to the class of hard, brittle metallic compounds with high melting points. This material exists primarily in research and specialized aerospace contexts, where its exceptional high-temperature stability and low density relative to its strength make it attractive for extreme-environment applications. ThAl3 is notable among intermetallic candidates for its potential in advanced propulsion systems and nuclear applications, though practical use remains limited due to manufacturing challenges and the handling requirements associated with thorium's radioactive properties.

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.
