2017-T4/T451 Aluminum Sheet
2017 Aluminum sheet description
2017 Aluminum sheet belongs to the Al-Cu-Mg series, which is a typical aluminum alloy, has a large market. High strength and great resistance of heat is the characteristics of 2017 aluminum, if the temperature is over 125°C, the 2017 alloy can have a higher strength than 7075 alloy.
2017 alloy is the first one of 2000 series can be used for industrial application wiht high strength and good cutting processing properties, copper is added to 2017 aluminum alloy, which is another feature of 2017.
2017 Aluminum sheet application
2017 Aluminum sheet is widely used for screw machine products, aircraft structures, rivets, card wheel hub, propeller components and other various structures.

2017 Aluminum sheet heat treatment
The 2017 alloy can be solutioo annealed at 940 F for three or four hours followed by water quench. Age hardening then occurs at room temperature and this produces the T4 temper. The "O" temper results from a 775 F treatment for three hours, controlled cooling at 50 F per hour down to 500 F, then air cool.
