Title (EN) ALUMINUM ALLOY
(FR) ALLIAGE D"ALUMINIUM
Abstract: front page image
(EN)A 7000 series aluminum alloy characterized by high strength, high fatigue resistance and high fracture toughness consists essentially of 5.9 to 6.9% zinc, 2.0 to 2.7% magnesium, 1.9 to 2.5% copper, 0.08 to 0.15% zirconium, a maximum of 0.15% iron, a maximum of 0.12% silicon, a maximum of 0.06% titanium, a maximum of 0.04% chromium, a maximum of 0.05% for each of any other trace elements present in the alloy, the total of the other trace elements in the alloy being a maximum of 0.15%, the balance of the alloy being aluminium. The foregoing alloy is hot worked to provide a wrought product, such as an extruded or plate product, in which recrystallization is held to a minimum. The wrought product is subjected to a solution treatment, quench, and elevated temperature aging cycle, normally until the product is at or near its maximum strength.
(FR)Un alliage d"aluminium de la serie 7000 caracterise par une haute resistance mecanique, une resistance elevee a la fatigue et une ductilite a la cassure elevee comprend essentiellement 5,9 a 6,9% de zinc, 2,0 a 2,7% de magnesium, 1,9 a 2,5% de cuivre, 0,08 a 0,5% de zirconium, un maximum de 0,15% de fer, un maximum de 0,12% de silicium, un maximum de 0,06% de titane, un maximum de 0,04% de chrome, un maximum de 0,05% pour chacun des autres elements eventuels presents a l"etat de traces dans l"alliage, le total des autres elements a l"etat de trace dans l"alliage etant de 0,15% au maximum, la balance etant l"aluminium. L"alliage decrit ci-dessus est travaille a chaud pour obtenir un produit forge, tel qu"un produit d"extrusion ou en plaque, dans lequel la recristallisation est maintenue a un minimum. Le produit forge est soumis a un traitement de mise en solution, a un refroidissement brusque et a un cycle de vieillissement a temperature elevee, normalement jusqu"a ce que le produit atteigne ou soit pres de sa resistance maximum.
