CoSn3
metal· JVASP-140720· CoSn3
CoSn3 is an intermetallic compound in the cobalt-tin system, representing a hard, brittle metallic phase that forms at specific composition ratios. This material is primarily encountered in solder joint microstructures, electronic interconnect research, and high-temperature metallic systems where cobalt and tin interact, though it is not commonly used as a primary engineering material in its pure form. Interest in CoSn3 stems from phase diagram studies and thermal fatigue behavior in lead-free solder applications, where understanding intermetallic growth and brittleness is critical to reliability; engineers encounter it as a secondary phase that can affect joint longevity rather than as a specified bulk 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.
