· JVASP-111630· SmCo4B4

SmCo4B4 is an intermetallic compound combining samarium (a rare-earth element) with cobalt and boron, representing a specialized metallic material in the rare-earth alloy family. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in high-performance magnetic, structural, or catalytic systems where rare-earth elements provide unique electronic or magnetic properties. Engineers would consider SmCo4B4 for demanding environments requiring the combination of rare-earth functionality with enhanced stiffness and density, though material availability, cost, and processing complexity typically limit adoption to advanced aerospace, defense, or specialized electronics applications.

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.
