· Al0.5Co0.2Ni0.3

Al₀.₅Co₀.₂Ni₀.₃ is a multi-principal element alloy (MPEA) or high-entropy alloy (HEA) precursor combining aluminum, cobalt, and nickel in near-equimolar proportions. This composition sits at the intersection of lightweight aluminum metallurgy and transition-metal strengthening, making it a research-phase material investigated for high-temperature structural applications where conventional superalloys or aluminum alloys fall short. The cobalt and nickel additions enhance thermal stability and strength retention, while the aluminum content aims to reduce density compared to fully refractory systems.

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.
