SrAl4
metal· JVASP-15054· SrAl4
SrAl4 is an intermetallic compound in the strontium-aluminum system, representing a high-performance metallic phase with a defined crystal structure combining the lightweight properties of aluminum with the chemical characteristics of strontium. While not widely used in conventional engineering, SrAl4 belongs to a class of intermetallic compounds that are subjects of active materials research for potential applications requiring specific stiffness-to-weight ratios, thermal management, or unique electromagnetic properties. The material's composition and phase chemistry make it relevant for exploratory work in aerospace, electronic packaging, and advanced composites rather than high-volume production.

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.
