2017 is a typical hard aluminum alloy in the aluminum copper magnesium system, with reasonable composition and good comprehensive properties. Many countries produce this alloy, which is the largest amount of duralumin. The alloy is characterized by high strength and certain heat resistance. It can be used as working parts below 150 ° C. When the temperature is higher than 125 ° C, the strength of 2017 alloy is higher than that of 7075 alloy. It is widely used in aircraft structures, rivets, truck hubs, propeller components and other structural parts.
2017 aluminum alloy plate has high strength and good machining performance, but poor corrosion resistance. two ××× Series aluminum plates are characterized by high hardness, of which the original content of copper is the highest, about 3-5%. two ××× Series aluminum plate belongs to aviation aluminum material, which is not often used in conventional industry.
2017 aluminum alloy plate is usually applied to rivets, general mechanical parts, aircraft, ships, transportation, building structural parts, transportation vehicle structural parts, propeller components and accessories, etc.
2017 aluminum alloy plate t451 has good formability in the state of annealing and new quenching, and the heat treatment strengthening effect is remarkable, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; Cracks are easy to occur during welding, but special processes can be used for welding or riveting.
