2A14 aluminum alloy plate is a metal material used in occasions that require high strength and hardness (including high temperature). The
2A14 aluminum alloy plate is characterized by high hardness, among which the copper content is the highest, about 3-5%. 2A14 aluminum alloy sheet is aerospace aluminum, which is not often used in conventional industries. With the development of the aerospace industry, the aluminum plate production technology of the 2A14 series will be further improved. Aircraft heavy-duty, forgings, thick plates and extruded materials, wheels. And structural elements, multi-stage rocket first-stage fuel tank and spacecraft parts, truck frame and suspension system parts.

Performance advantages of
2A14 aluminum alloy plate: A: The elongation is more than 10%, the hardness can reach 135HB, and the natural aging is long, which can reach 15h. B: Good machinability, good electrical resistivity, spot welding and seam welding performance. C: Like 2A11 aluminum plate, it is a hard aluminum alloy with high strength and good thermal conductivity, and can be used for thermal treatment. D: The cutting edge quality of the aluminum plate is good, without burrs, tower shape, and layer channeling. It is widely used in aircraft structures (skins, skeletons, rib beams, bulkheads, etc.), rivets, missile components, truck wheels, propeller components and various other structural parts. Used as structural rivets whose working temperature does not exceed 100℃.
