· JVASP-9076· Sr5Al9

Sr5Al9 is an intermetallic compound in the strontium-aluminum system, representing a specific stoichiometric phase within the Sr-Al binary system. This material belongs to the family of lightweight intermetallic compounds and is primarily of research and development interest rather than established commercial production. Sr5Al9 and related Sr-Al phases are investigated for potential applications in high-temperature structural materials, thermal management systems, and as precursors for advanced ceramic or composite materials, leveraging the low density characteristic of aluminum-based intermetallics combined with strontium's thermal and chemical properties.

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.
