· JVASP-82008· HfScAu2

HfScAu2 is a ternary intermetallic compound combining hafnium, scandium, and gold—a research-phase material rather than an established commercial alloy. This composition falls within the broader class of high-entropy and lightweight intermetallics being explored for extreme-environment applications where conventional alloys reach their limits. The material's low density combined with the refractory properties of hafnium suggests potential for high-temperature structural use, though engineering adoption remains limited pending further characterization of mechanical properties, processability, and cost-benefit analysis against competing alternatives.

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.
