Al₀.₃₃Co₀.₂Ni₀.₄₇ is a multi-principal element alloy (MPEA) or high-entropy alloy (HEA) composed of aluminum, cobalt, and nickel in near-equimolar proportions. This is primarily a research-phase material studied for its potential to combine lightweight properties from aluminum with the strength and thermal stability of transition metals, representing the emerging class of compositionally complex alloys designed to overcome limitations of conventional binary and ternary systems. Industrial adoption remains limited, but this material family shows promise in aerospace, automotive, and high-temperature structural applications where weight reduction and mechanical performance at elevated temperatures are critical.
