· Y27Al18Ni55

Y27Al18Ni55 is an experimental intermetallic compound based on the yttrium-aluminum-nickel ternary system, representing a research-phase material rather than an established commercial alloy. This composition lies within a family of materials being investigated for high-temperature structural applications, where the combination of rare-earth (yttrium), light metal (aluminum), and transition metal (nickel) elements is designed to achieve improved strength-to-weight ratios and oxidation resistance. The material remains primarily in the materials research domain, with potential relevance to aerospace and energy sectors if performance characteristics prove viable compared to established superalloys and intermetallic 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.
