· Th6 Al4

Th6Al4 is an experimental intermetallic compound combining thorium and aluminum, belonging to the family of refractory metal alloys. This material is primarily of research interest for high-temperature structural applications where conventional superalloys reach their limits, though its development and deployment remain limited due to thorium's radioactive nature and associated handling restrictions. Engineers would consider this compound only in specialized aerospace or nuclear contexts where extreme thermal stability and specific strength are critical and regulatory frameworks permit its use.

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.
