· JVASP-109794· AlNi4As3

AlNi4As3 is an intermetallic compound in the aluminum-nickel-arsenic system, representing a research-phase material rather than a widely commercialized alloy. This ternary compound belongs to the family of metal arsenides and aluminum-nickel intermetallics, which are primarily investigated for their potential in high-temperature applications, semiconductor applications, or specialized coating systems where combined properties of aluminum, nickel, and arsenic offer advantages over binary alternatives.

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.
