· Al4NiY

Al4NiY is an intermetallic compound combining aluminum, nickel, and yttrium, belonging to the family of high-temperature aluminum-based intermetallics. This material is primarily of research and development interest rather than widespread commercial production, investigated for potential applications requiring exceptional strength-to-weight ratios and thermal stability at elevated temperatures. It represents an emerging candidate in the broader effort to develop lightweight structural materials that can operate beyond conventional aluminum alloy limits, with particular relevance to aerospace and advanced thermal applications where yttrium additions provide oxidation and creep resistance.

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.
