· JVASP-35412· SiAgPt5

SiAgPt5 is a silver-platinum alloy with silicon addition, belonging to the precious metal alloy family. This material is primarily developed for high-reliability applications requiring excellent electrical and thermal conductivity combined with corrosion resistance, such as electrical contacts, bonding layers in microelectronics, and dental or medical device components where biocompatibility and durability are critical. The platinum content provides superior oxidation resistance and chemical inertness compared to silver-only alternatives, while the precise role of silicon—likely as a minor strengthening or refining agent—warrants verification against the supplier's technical documentation.

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.
