Abstract (en)
[origin: CA3184620A1] The invention relates to the use of a wrought T8 aluminium alloy product with the following composition, in wt%, Cu: 3.6 4.4; Mg: 1.2 1.4; Mn: 0.5 0.8; Zr: = 0.15; Ti: 0.01 0.15; Si = 0.20; Fe = 0.20; Zn = 0.25; other elements < 0.05; the remainder being aluminium, in an application in which the product is kept at temperatures of between 80°C and 250°C for a significant period of at least 200 hours. The products intended for the use according to the invention are particularly useful in an application such as a rotor or another component of an air suction pump such as, in particular, a vacuum pump.
