Non-evaporable getter alloys Zr-Co-A are disclosed wherein A is an eleme nt selected among Yttrium, lanthanum, rare earths or mixtures thereof They may be activated at relatively low temperature and are capable of sorbing a wide variety of gases. Furthermore, the alloys of the invention are safer from the environmental and safety point of view with respect to other similar alloys, in that not containing metals which are toxic or capable of forming toxic compounds, and reaching i n case of violent reaction with reactive gases lower temperatures with respect to known getter alloys.
