Aluminum 2219 has a good machinability and good mechanical properties.Aluminum 2219 is an age-hardenable copper containing alloy of aluminum.Aluminum 2219 is typically used in high temperature, structural applications and in high strength elements.
Aluminum alloy 2219 is a high strength alloy which combines good machinability and good mechanical properties. 2219 is useful over a temperature range of -452° F to -600° F, IS readily weldable and has good fracture toughness.In the T8 condition it is resistant to stress corrosion cracking. Aluminum 2219 is typically used in a range of aerospace applications such as high temperature structural applications including space booster and fuel tanks.
This alloy was not designed for hot working; it is best used for cold working and is machinable in the annealed condition. Hot working and welding adversely affect this alloy’s ability to resist corrosion.If welded or hot worked, this alloy must be heat treated to restore corrosion resistance. Heat treatment can be performed at 1000 °F, followed by a cold water quench.
Some of Aluminum Alloy 2219’s common applications include structural components for harsh, high temperature environments, as well as higher strength weldments. As a raw material, it is available in flat rolled products, forging products, and shapes.
Our alloys meet or exceed the industry’s toughest standards, including all applicable AMS, ASTM, MIL, QQ, and SAE applications, and more.
