· JVASP-109738· Hf2Al3Au

Hf2Al3Au is an intermetallic compound combining hafnium, aluminum, and gold in a defined stoichiometric ratio. This is a research-phase material studied for its potential in high-temperature structural applications and specialized alloy development, belonging to the broader family of refractory intermetallics that leverage hafnium's exceptional heat resistance. The inclusion of gold suggests investigation into thermal stability, oxidation resistance, or electronic properties in extreme environments where conventional nickel- or cobalt-based superalloys reach their 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.
