2017 Aluminum Alloy Sheet
2017 aluminum alloy belongs to 2000 series alloy which obtain industrial application in earliest. It has high strength and good cutting performance, but its corrosion resistance is poor. 2017 aluminum alloy is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is reasonable and the overall performance is better. It is the largest amount of hard aluminum.
2017 aluminum alloy is characterized by high strength and certain heat resistance, which can be used as working parts below 150°C. The temperature is higher than 125°C, and the strength of the 2017 alloy is higher than that of the 7075 alloy. The heat treatment, annealing and new quenching conditions have better forming properties, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by covering with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by special technology.
It is widely used in aircraft structures, rivets, truck wheels, propeller components and various other structural parts. 2017 aluminum alloy has better forming properties in the annealed and quenched states, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by covering with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by special technology.
2017 aluminum is a 2000-series aluminum alloy: the main alloying addition is copper, and it is formulated for primary forming into wrought products. 2017 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-2017. AlCu4MgSi is the EN chemical designation. And A92017 is the UNS number.
It has been in use since 1916, but has only received its standard designation in 1954. The properties of 2017 aluminum include six common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 2017 aluminum to: 2000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
