Treatable 7xxx Aluminum Alloys. For aluminum alloys in the 7xxx series, zinc is commonly the alloying agent although small quantities of copper, magnesium and chromium may also be added to make it heat treatable. These alloys, when combined with aluminum, make an extremely strong material used primarily in commercial aircraft
The commercial heat-treatable alloys are, with few exceptions, based on ternary or quaternary systems with respect to the solutes involved in developing strength by precipitation. Commercial alloys whose strength and hardness can be significantly increased by heat treatment include 2xxx, 6xxx, and 7xxx series wrought alloys and 2xx.0, 3xx.0 and
Non-heat treatable and heat treatable alloys are two main groups of aluminium alloys. Non-heat treatable alloy categories (1xxx, 3xxx and 5xxx) are not strengthened by second-phase particles and usually are called non-precipitation hardening alloys. The strengthening methods for these alloys include cold working (strain hardening) or refining
From International heat treat consultant David Pye, of Pye Metallurgical we have these thoughts about the heat treatment of heat treatment of heat treatable aluminum alloys is a very sensitive and specialized subject. The strengthening of the heat treatable alloys necessitates what would appear to be a very simple procedure known as

Typically, the common heat-treatable base alloys, such as 6061-T6, lose a substantial proportion of their mechanical strength after welding. For example, 6061-T6 typically has 45,000 PSI tensile strength prior to welding and around 27,000 PSI in the as-welded condition. One option with the heat-treatable alloys is post weld heat-treatment to

heat treatable aluminum alloys, precipitates provide the main strengthening mechanism whereas grain size and deformation hardening usually play a secondary role. As dislocations are the preferable sites for decomposition of oversaturated solid solutions, plastic deformation is an effective way to control precipitate size and
series aluminium alloys are high strength, heat treatable alloys containing zinc and magnesium as the main alloying elements. Similar to all heat treatable aluminium alloys, 7xxx series alloys rely on precipitation hardening to improve properties This series of alloys can be divided into Al-Zn-Mg and Al-Zn-Mg-Cu alloys

treatable alloys can be hardened by cold work. The degree of work hardening is designated by the Temper. Heat treatable alloys (the 2000, 6000, and 7000 series) are able to be solution treated and then
A method is described of thermally treating the 7,000 series aluminum alloys that have been subjected to a solution heat treatment at a high temperature and then to an ageing treatment at a lower temperature, thereby hardening the alloy but likewise producing therein a susceptibility to stress-corrosion cracking. The novel method comprises the steps of (1) subjecting the alloy to a

NON-HEAT-TREATABLE ALLOYS. Wrought compositions that do not respond to strengthening by heat treatment mainly comprise the various grades of aluminium as well as alloys with manganese or magnesium as the major additions, either singly or in combination (Table 3.2). Approximay of all aluminium flat rolled products (sheet, plate and
