  2. 7075 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/7075_aluminium_alloy

    7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility ...

    Perhaps there should be some information on this. --petebachant 19:31, 17 July 2013 (UTC) []It basically isn't weldable, though a bit of work with friction-stir welding of 7075-0 is showing that there may be some promise along those lines.

  4. Aluminium–copper alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–copper_alloys

    Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements.Important grades also contain additives of magnesium, iron, nickel and silicon (AlCu(Mg, Fe, Ni, Si)), often manganese is also included to increase strength (see aluminium-manganese alloys).

  5. Weldability - Wikipedia

    en.wikipedia.org/wiki/Weldability

    Many metals and thermoplastics can be welded, but some are easier to weld than others (see Rheological weldability). A material's weldability is used to determine the welding process and to compare the final weld quality to other materials. Weldability is often hard to define quantitatively, so most standards define it qualitatively.

  6. 7050 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/7050_aluminium_alloy

    Welding should be avoided, because it weakens aluminum alloy. [2] Applications. Aircraft and other structures [1] Fuselage frames [2] Bulkheads [2] Wing skins [3]

  7. 2024 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/2024_aluminium_alloy

    It is weldable only through friction welding, and has average machinability. Due to poor corrosion resistance, it is often clad with aluminium or Al-1Zn for protection, although this may reduce the fatigue strength. [1] [2] In older systems of terminology, 2XXX series alloys were known as duralumin, and this alloy was named 24ST.

  8. Aluminium–lithium alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–lithium_alloys

    Consisting of alloys that were meant to replace the popular 2024 and 7075 alloys directly, the second generation of Al–Li had high lithium content of at least 2%; this characteristic produced a large reduction in density but resulted in some negative effects, particularly in fracture toughness. The third generation is the current generation ...

  9. Aluminium–scandium alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–scandium_alloys

    The addition of scandium to aluminium limits grain growth in the heat-affected zone of welded aluminium components. This has two beneficial effects: the precipitated Al 3 Sc forms smaller crystals than in other aluminium alloys, [2] and the volume of precipitate-free zones at the grain boundaries of age-hardening aluminium alloys is reduced. [2]
