2014 aluminum sheet due to the high content of the main alloy component Cu, so in the 2 series Al-Cu-Mg alloy, its strength is higher and the heat strengthening effect is obvious. Similarly, 2014 aluminum alloy is a hard aluminum alloy, but it is also a wrought aluminum alloy. Overall, 2014 aluminum properties showed good machinability, spot welding and roll welding effects, and extrusion effects. However, in the hot state, the plasticity of the 2014 aluminum sheet is slightly weaker, and the corrosion resistance is also weaker. The surface needs to be coated with aluminum to increase its corrosion resistance. At present, 2014 aluminum alloy is widely used in applications requiring high strength and hardness (including high temperature), such as: heavy aircraft, forgings, thick plates and extruded materials, wheels and structural elements, truck frame and suspension system parts.
1. Weldability. The contact welding, spot welding and roll welding of 2014 aluminum sheet are good, but arc welding and gas welding are not ideal.
2. Machinability. Similarly, the 2014 aluminum alloy can perform turning, milling, boring, planing and other mechanical processing at the maximum speed that most machine tools can reach.
3. Squeezable. It is worth mentioning, 2014 aluminum sheet is one of the few plates in the 2 series alloy that has an extrusion effect, It is well extruded into various extruded materials and widely used.
4. Mechanical Properties. 2014 aluminum alloy has tensile strength≥440MPa, elongation≥10 (%), which is under AISI standard.
Conventional Application
There are many general applications of 2014 aluminum sheet, including molds, rivets, high-strength structural parts, thick plates, heavy forgings, extruded materials, truck wheels, truck frame and suspension system parts, multi-stage rocket first-stage fuel tank, aerospace parts, other occasions requiring high strength and hardness (including high temperature). Besides, it was also used in the fields of oxygen production equipment and shipbuilding,etc.
2014 Aluminum Sheet for Aircraft Manufacturing
2014 aluminum sheet, as 2 series aluminum for aerospace, is widely used in aircraft structure manufacturing, such as aircraft skins, skeletons, ribs, bulkheads, etc., propeller elements and other aerospace equipment structural parts.
