· Al0.4Co0.05Ni0.55

Al₀.₄Co₀.₀₅Ni₀.₅₅ is a multi-principal element alloy (MPEA) or high-entropy alloy (HEA) in the Al-Co-Ni system, representing an emerging class of metallic materials designed with multiple alloying elements in near-equimolar or balanced compositions. This material is primarily a research compound studied for its potential to achieve unusual combinations of strength, ductility, and thermal stability that conventional binary or ternary alloys cannot easily match. The Al-Co-Ni family is of particular interest for elevated-temperature applications where conventional superalloys face cost or weight constraints.

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.
