· Ca3Au

Ca3Au is an intermetallic compound combining calcium and gold in a 3:1 stoichiometric ratio, belonging to the family of lightweight metallic intermetallics. This material is primarily of research and academic interest rather than established commercial production, with potential applications in advanced alloys where the combination of low density with metallic bonding characteristics could be exploited. Engineers considering this compound should recognize it as an experimental material that may offer novel property combinations in specialized aerospace or high-performance applications, though its scarcity, cost, and limited processing knowledge make it unsuitable for conventional engineering projects.

Export Control

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.
