· JVASP-56317· CuBi

CuBi is a copper-bismuth binary alloy that combines copper's excellent electrical and thermal conductivity with bismuth's unique properties, such as low melting point and high density. This material is primarily of research and specialized industrial interest, used in applications requiring low-temperature joining, fusible alloys, and thermal management systems where bismuth's non-toxic characteristics are advantageous over traditional lead-based alternatives.

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.
