Abstract (en)
[origin: WO2021077209A1] There is provided an extruded and brazed product with improved corrosion resistance by having low coarse recrystallized grain formation as well as a method for making same. The extruded and brazed product comprises an aluminum alloy comprising in weight percent Mn 0.6 – 0.75; Fe 0.11 – 0.16; Si 0.10 – 0.19; Cu < 0.01; Zn < 0.05; Ti < 0.05; optionally a grain refiner; optionally Ni < 0.01; and the balance being aluminum and inevitable impurities.
