· CoNiSn

CoNiSn is a ternary intermetallic alloy combining cobalt, nickel, and tin, belonging to the family of high-strength metallic compounds. This material is primarily investigated in research contexts for applications requiring excellent hardness and wear resistance, with particular interest in advanced coating systems, wear-resistant components, and potential high-temperature structural applications. The combination of these elements leverages cobalt's strength and temperature stability, nickel's toughness and corrosion resistance, and tin's hardening contribution, making it an alternative to conventional precipitation-hardened superalloys in specialized scenarios.

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.
