· SmCo3B2

SmCo3B2 is a samarium-cobalt intermetallic compound belonging to the rare-earth transition metal boride family. This material combines rare-earth hardness with metallic bonding characteristics, making it a candidate for high-performance applications requiring thermal stability and wear resistance. While primarily a research and specialty material rather than a commodity alloy, SmCo3B2 represents the broader potential of rare-earth boride systems for extreme-environment engineering where conventional superalloys or ceramics fall short.
