Brief Introduction Of 2024 aluminum :
2024 is the oldest of all aircraft aluminum alloy with the main alloying element being copper. They require solution heat-treatment to obtain optimum properties. Applications that require high strength to weight ratio, as well as good fatigue resistance. It is weldable only through friction welding, and has average machinability. Due to its high strength and fatigue resistance, 2024 is widely used in aircraft structures, especially wing and fuselage structures under tension. 2024 comes in different tempers.
Brief Introduction Of 2024 aluminum alloy:
Aluminium alloy 2024 is an aluminium alloy, with copper as the primary alloying element. It is used in applications requiring high strength to weight ratio, as well as good fatigue resistance. 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.In older systems of terminology, this alloy was named 24ST.
2024 is commonly extruded, and also available in alclad sheet and plate forms. It is not commonly forged.
Annealing:
Aluminium/Aluminum 2024 alloy is annealed from a heat treated condition between 399 and 427°C (750 and 800°F) for about 2 hours and then cooled slowly in the furnace. This alloy can be annealed between cold working operations at 343°C (650°F) for 2 hours after which the alloy is cooled in air.
Cold Working:
Conventional methods are used for cold working Aluminium / Aluminum 2024 alloy. For a sheet that is 1/4" thick, or thinner bend radii of 1/2 to 1 times thickness are suitable. Ductility in the annealed condition is best suited for this alloy. Bend radii of five to six times thickness are suitable for T3 or T4 conditions.
Welding:
Inert gas consumable electrode arc method or resistance welding is used to weld Aluminium / Aluminum 2024 alloy. In general, welding of any kind is not recommended for Aluminium / Aluminum 2024 alloy due to degradation of corrosion resistance that occurs as a result of weld heat. If this alloy is welded then the heat treatment should be repeated.
Available Shapes: Standard profiles include Angle, Channels, Tee's, Hats, seat track and special shapes.
Tempers include: T3 and T3511, T8511 (both T3 and T3511 meet the requirements of T4)
