CoSn2
metal· CoSn2
CoSn2 is an intermetallic compound formed from cobalt and tin, belonging to the family of binary metallic intermetallics. It exhibits moderate elastic stiffness with notable anisotropic behavior, making it relevant for specialized applications where intermetallic phases contribute to overall alloy performance rather than serving as a primary structural material. This compound is typically encountered as a constituent phase in tin-based solder systems, coating materials, and high-temperature alloys, where its presence influences mechanical properties and thermal stability of the 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.
