· JVASP-125551· SrAl3

SrAl₃ is an intermetallic compound in the strontium-aluminum system, representing a binary metallic phase rather than a conventional alloy. This material exists primarily in research and experimental contexts, where it is studied for its potential in lightweight structural applications and as a precursor or additive phase in aluminum-based composites; its notable characteristic is the incorporation of strontium, which can modify grain structure and improve certain mechanical properties in aluminum casting systems. The compound is not established as a commodity engineering material but rather represents a research avenue into intermetallic strengthening mechanisms and the behavior of alkaline-earth elements in aluminum matrices.

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.
