· Ca5Au4

Ca5Au4 is an intermetallic compound combining calcium and gold, representing a rare-earth-free metallic system with potential for structural or functional applications requiring specific stiffness and density characteristics. This material exists primarily in research and development contexts rather than established industrial production, with investigation likely focused on understanding phase stability, mechanical behavior, and potential applications in advanced alloys or specialized engineering domains. The calcium-gold system is of interest to materials scientists exploring novel intermetallic chemistries, though widespread commercial adoption remains limited due to cost, processing complexity, and availability relative to conventional engineering metals.

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.
