· Sr1 Au5

Sr1Au5 is an intermetallic compound combining strontium and gold, classified as a semiconductor material within the metallic intermetallic family. This is a research-phase compound rather than a widely commercialized engineering material; intermetallics of this type are of interest for their unique electronic properties arising from ordered crystal structures that blend metallic and semiconducting character. Sr1Au5 belongs to a broader class of rare-earth and alkaline-earth gold intermetallics being investigated for thermoelectric, optoelectronic, and high-temperature electronic device applications where conventional semiconductors 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.
