text: A variety of alloys exhibit the shape-memory effect. Alloying constituents can be adjusted to control the transformation temperatures of the SMA. Some common systems include the following (by no means an exhaustive list):
  * Ag-Cd 44/49 at.% Cd
  * Au-Cd 46.5/50 at.% Cd
  * Co-Ni-Al
  * Co-Ni-Ga
  * Cu-Al-Be-X(X:Zr, B, Cr, Gd)
  * Cu-Al-Ni 14/14.5 wt.% Al, 3/4.5 wt.% Ni
  * Cu-Al-Ni-Hf
  * Cu-Sn approx. 15 at.% Sn
  * Cu-Zn 38.5/41.5 wt.% Zn
  * Cu-Zn-X (X = Si, Al, Sn)
  * Fe-Mn-Si
  * Fe-Pt approx. 25 at.% Pt
  * Mn-Cu 5/35 at.% Cu
  * Ni-Fe-Ga
  * Ni-Ti approx. 55–60 wt.% Ni
  * Ni-Ti-Hf
  * Ni-Ti-Pd
  * Ni-Mn-Ga
  * Ni-Mn-Ga-Cu
  * Ni-Mn-Ga-Co
  * Ti-Nb
