The alloys Cu 78,3% - Al 9,8% - Mn 11,9 and 77.5% Cu - Al 9.8% - Mn 11,9% -% Nb 0.5 - 0.3% Ni (wt%) were prepared without the use of protective atmosphere. The first alloy was characterized using optical microscopy, scanning electron microscopy, differential scanning calorimetry and X-ray diffraction and its mechanical property was determinated by the tensile test, quantification of the shape memory effect and superelasticity. In the case of alloy with Nb and Ni, this was characterized by optical microscopy, differential scanning calorimetry and had their mechanical properties determined by tensile testing.
