· JVASP-154415· K3Sn4Au

K3Sn4Au is an intermetallic compound combining potassium, tin, and gold in a defined stoichiometric ratio. This is a research-phase material rather than an established commercial alloy, belonging to the family of ternary intermetallics that combine precious and base metals to engineer specific crystal structures and electronic properties. Such compounds are investigated for applications requiring tailored hardness, electrical conductivity, or corrosion resistance that differ substantially from their constituent elements.

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.
