2017 aluminum plate is a common aerospace aluminum material. It is the first 2 series aluminum alloy to obtain industrial application. It has high strength and good cutting performance, but has poor corrosion resistance.
The 2 series aluminum plate is characterized by high hardness, and the copper metal content is the highest, about 3-5%. The 2 series aluminum plates are aerospace aluminum materials and are currently not commonly used in conventional industries.
The
2017 aluminum plate is a typical hard aluminum alloy in the aluminum-copper-magnesium system, which has reasonable composition and good comprehensive performance. This alloy is produced in many countries and is the most used in hard aluminum. The alloy is characterized by high strength and a certain heat resistance, and can be used as a working part below 150 °C. At temperatures above 125 ° C, the strength of the 2017 alloy is higher than that of the 7075 alloy. The forming properties are better in the hot state, annealing and new quenching conditions, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. Corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; it is easy to crack when welding, but it can be welded or riveted by special process. Widely used in aircraft structures, rivets, truck hubs, propeller components and other structural components.
