The invention relates to a process to manufacture a clad strip, <1.5 mm
thick, intended for the manufacture of brazed heat exchangers, comprising:
casting of a plate made of core alloy composed as follows (o by weight):
Si<0.8 Fe<0.8 Cu: 0.2-0.9 Mn: 0.7-1.5 Mg<0.4 Zn<0.2 Ti<0.1
other elements <0.05 each and <0.15 in total, the remainder
aluminum,
homogenization of said plate between 550 and 630.degree. C. for at least
one hour,
cladding on one or two sides of said blank of a brazing aluminum alloy,
preferentially containing 5 to 13% silicon,
hot rolling followed by cold rolling of the plated blank to a thickness
close to the final thickness,
recrystallization annealing of the strip between 300 and 4000C.,
strain hardening of the annealed strip to obtain a permanent deformation
between 2 and 10% and the final thickness.
