Spangold is a family of shape memory-effect alloys (SME) of gold, copper, and aluminum in either 18K or 23K. The name of the family is a play on the word "spangled". Spangold is a beta-phase alloy with a nominal stoichiometry of Au7Cu5Al4 and a nominal composition by mass of 76% gold, 18% copper, and 6% aluminum. The texture is caused by the induction of a martensitic-type phase transformation on a polished surface. Spangold undergoes a martensitic-type phase transformation when properly treated
