· JVASP-125482· Al3As

Al₃As is an intermetallic compound in the aluminum-arsenic system, representing a brittle metallic phase that forms at specific composition ratios. This material is primarily of research and academic interest rather than a mainstream engineering material; it appears in phase diagram studies and materials science investigations of aluminum-arsenic interactions, but sees minimal industrial production or application due to its brittle nature and the toxicity concerns associated with arsenic-containing compounds.

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.
