· CoGe

CoGe is an intermetallic compound combining cobalt and germanium, belonging to the family of transition metal–metalloid compounds. This material exists primarily in research and exploratory contexts rather than as an established commercial alloy, with potential applications in thermoelectric devices, magnetic materials, and semiconductor technologies where the electronic structure and thermal properties of cobalt-germanium systems are exploited.

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.
