· Sm3AlN

Sm₃AlN is an intermetallic nitride compound combining samarium (a rare-earth element) with aluminum and nitrogen, representing an emerging class of lightweight refractory materials. This material belongs to the family of rare-earth metal nitrides and is primarily of research interest rather than established high-volume production, with potential applications in extreme-temperature structural components where conventional alloys reach their thermal limits. Engineers would consider this compound for advanced aerospace, nuclear, or high-temperature industrial settings where the combination of low density, high stiffness, and nitride stability offers advantages over titanium aluminides or nickel superalloys in specialized thermal environments.

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.
