Al0.52Co0.18Ni0.3

Al0.52Co0.18Ni0.3 is a high-entropy alloy (HEA) or multi-principal element alloy combining aluminum, cobalt, and nickel as major constituents. This is primarily a research material designed to exploit the unique phase stability and property combinations that emerge from equiatomic or near-equiatomic mixing of multiple transition metals with aluminum. The Al-Co-Ni system is investigated for lightweight high-temperature applications where conventional superalloys fall short, particularly in aerospace and thermal management contexts where the lower density of aluminum-rich compositions offers weight savings over nickel-based or cobalt-based alternatives.
