NiFeAl

NiFeAl is an intermetallic compound combining nickel, iron, and aluminum, typically explored as a lightweight structural material with potential for elevated-temperature applications. Research-grade alloys in this family are investigated for aerospace and power generation contexts where low density and high-temperature strength are valuable, though they generally remain under development compared to established superalloys. The NiFeAl system represents an alternative approach to achieving strength-to-weight performance by leveraging intermetallic ordering, particularly where cost or manufacturability advantages over conventional nickel-based superalloys may apply.
