Title:
ろう付けされる熱交換器の製造のための、アルミニウム合金でクラッドされるストリップの製造方法
Document Type and Number:
Japanese Patent JP4000190
Kind Code:
B2
Abstract:
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 (% 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 aluminium, homogenization of said plate between 550 and 630° C. for at least one hour, cladding on one or two sides of said blank of a brazing aluminium 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 400° C., strain hardening of the annealed strip to obtain a permanent deformation between 2 and 10% and the final thickness.
