· JVASP-149032· In2Cu

In₂Cu is an intermetallic compound combining indium and copper in a 2:1 ratio. This material belongs to the family of indium-copper intermetallics, which are of primary interest in microelectronics and materials research rather than bulk structural applications. In₂Cu and related indium-copper phases are investigated for solder materials, contact metallurgy, and thin-film applications where the controlled formation of intermetallic layers is critical to device reliability and performance.

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.
