A shape-memory admixture (SMA, acute metal, anamnesis metal, anamnesis alloy, beef wire, acute alloy) is an admixture that "remembers" its original, cold-forged shape: abiding the pre-deformed appearance by heating.

Shape-memory alloys accept applications in industries including medical and aerospace.
