NiTiCu and NiTiCo shape memory alloys are characterized in view of dental and medical applications. A binary alloy is taken as a reference. In this work we studied specially the efficient temperature ranges for such uses and the mechanical strength available from shape memory effect. Characteristic temperatures are determined by internal friction measurements while the mechanical behaviour is studied with the help of a "soft" torsion machine.
