· JVASP-122223· Al4Si2Mo3

Al4Si2Mo3 is an aluminum-based intermetallic compound containing silicon and molybdenum, representing a research-phase material in the family of advanced aluminum composites and intermetallics. This composition sits within the broader category of lightweight, high-temperature aluminum alloys being investigated for structural applications where improved stiffness and thermal stability are needed beyond conventional aluminum-silicon castings. The material's appeal lies in its potential to offer weight savings combined with elevated-temperature strength, though industrial adoption remains limited and the alloy is primarily found in academic research and aerospace/automotive feasibility studies.

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.
