Nickel Aluminide

An intermetallic compound where nickel and aluminum line up in perfect order. While ordinary metals soften with heat, Ni₃Al gains yield strength as temperature rises — a "yield strength anomaly." A fervent type who peaks under adversity, it re-grows its own Al₂O₃ protective film when damaged. Light yet strong at high temperature, an elite that powers jet engines, its ordered lattice symbolizing discipline and teamwork.
