· JVASP-125489· CaAl3

CaAl₃ is an intermetallic compound in the calcium-aluminum system, representing a lightweight metallic phase that combines low-density calcium with aluminum. While not widely commercialized as a standalone engineering material, CaAl₃ and related calcium-aluminum intermetallics are of research interest for lightweight structural applications and as potential reinforcement phases in aluminum-matrix composites, where their low density and high melting point offer advantages in aerospace and automotive contexts.

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.
