Abstract
In this paper, the production of SMA at TREFIMETAUX is described as well as the progressive change in the production of CuZnAl SMA to CuAlNi. We analyse the statistical dispersion of the transformation temperature of our hot extruded products and we precise the progresses obtained for three years. Remarks on hot transformation and heat treatments of CuAlNi at industrial scale complete this analysis.
