· Al21Pd8

Al₂₁Pd₈ is an intermetallic compound combining aluminum and palladium, belonging to the family of lightweight metallic compounds with ordered crystal structures. This material represents an experimental or specialized research composition rather than a widely commercialized alloy, and is of interest for applications requiring combined low density with enhanced strength and stiffness compared to conventional aluminum alloys. The palladium content imparts improved hardness and thermal stability, making it potentially relevant for aerospace, high-temperature structural applications, or catalytic uses where aluminum-palladium combinations show promise.

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.
