· Ho1 Hf1 Ru2

Ho1Hf1Ru2 is an intermetallic compound combining holmium, hafnium, and ruthenium in a 1:1:2 atomic ratio. This is a research-phase material within the rare-earth transition metal intermetallic family, explored primarily for high-temperature structural applications where conventional superalloys reach their limits. The combination of refractory elements (hafnium, ruthenium) with a rare-earth constituent (holmium) targets extreme-environment performance, though industrial deployment remains limited and material behavior is still being characterized.

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.
