· JVASP-130271· AgSn7

AgSn7 is a silver-tin alloy containing approximately 7% tin, belonging to the family of precious metal alloys commonly used in jewelry, electronics, and specialized bonding applications. This alloy offers improved strength and hardness compared to pure silver while maintaining excellent electrical and thermal conductivity, making it a practical choice when pure silver's softness limits performance. The tin addition enhances wear resistance and workability, positioning AgSn7 as a cost-effective alternative to higher-silver compositions in applications where moderate silver content is acceptable.

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.
