· Al0.4Nb0.33Ni0.2

Al₀.₄Nb₀.₃₃Ni₀.₂ is a multi-principal-element alloy (compositionally complex alloy or high-entropy alloy precursor) combining aluminum, niobium, and nickel in near-equimolar proportions. This material exists primarily in the research domain as a candidate for high-temperature structural applications, where the combination of lightweight aluminum with refractory niobium and strength-contributing nickel aims to balance density, strength, and thermal stability. Such compositions are of interest for aerospace and power-generation industries seeking alternatives to conventional superalloys, though industrial deployment remains limited pending maturation of manufacturing and performance validation.

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.
