CaCu5
metal· CaCu5
CaCu5 is an intermetallic compound in the calcium-copper system, forming a brittle metallic phase with relatively high density. This material belongs to the family of rare-earth-free intermetallics and is primarily of research interest for hydrogen storage applications, where similar calcium-copper phases show promise for absorbing and releasing hydrogen at moderate temperatures and pressures. Industrial adoption remains limited; the material is most relevant to materials scientists exploring next-generation energy storage systems as an alternative to conventional hydride materials, particularly where cost reduction or specific thermal cycling behavior is advantageous.

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.
