· Th4 Re8

Th4Re8 is an intermetallic compound composed of thorium and rhenium, representing a refractory metal system explored in high-temperature materials research. This material belongs to the family of transition metal intermetallics, which are investigated for extreme-temperature applications where conventional superalloys reach their limits. While primarily a research compound rather than an established commercial material, thorium-rhenium systems are of interest to aerospace and nuclear engineers seeking candidate materials for ultra-high-temperature structural applications, though practical adoption remains limited by thorium's radioactivity concerns and the cost and scarcity of rhenium.

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.
