· JVASP-37745· TmHfCo2

TmHfCo₂ is a ternary intermetallic compound combining thulium (rare earth), hafnium (refractory metal), and cobalt in a defined stoichiometric ratio. This material belongs to the family of high-entropy and complex intermetallics being explored in materials research for extreme-environment applications. While not yet in widespread industrial production, compounds of this composition are investigated for potential use in high-temperature structural applications, magnetic devices, and aerospace systems where conventional alloys reach performance limits.

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.
