· Y43Ag157

Y43Ag157 is a yttrium-silver intermetallic compound or alloy system, representing a high-silver composition within the Y-Ag phase diagram. This material falls into the rare-earth metal family and is primarily of research and specialized industrial interest rather than a commodity engineering material. Applications are likely limited to advanced electronic contacts, catalytic systems, or high-temperature joint materials where the combined properties of yttrium (reactivity, oxygen affinity) and silver (electrical/thermal conductivity, biocompatibility) offer specific advantages over conventional alternatives.

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.
