CoSn7
metal· JVASP-122555· CoSn7
CoSn7 is an intermetallic compound in the cobalt-tin system, representing a defined stoichiometric phase rather than a conventional solid solution alloy. This material is primarily of research and industrial interest in electronics and joining applications, where it serves as a solder constituent or intermetallic barrier layer in microelectronic packaging and thermal management systems. CoSn7 offers potential advantages in high-temperature stability and wear resistance compared to conventional tin-based solders, though it is typically encountered as a secondary phase in composite solder systems rather than as a monolithic engineering material.

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.
