· JVASP-117115· ThAl8Cu4

ThAl8Cu4 is a quaternary intermetallic compound combining thorium, aluminum, and copper—a research-phase material exploring high-temperature structural possibilities in the thorium-aluminum-copper system. While thorium-based alloys have historical aerospace applications, this specific composition appears to be an experimental intermetallic rather than a production engineering material; the material family is notable for investigating lightweight high-strength possibilities, though commercial deployment remains limited due to thorium's regulatory constraints and processing complexity. Engineers would consider this material primarily in specialized research contexts or advanced applications where thorium's nuclear properties, thermal stability, or unique phase chemistry offer advantages that conventional aluminum or copper alloys cannot match.

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.
