Aluminum 2219 is an age-hardenable copper containing alloy of aluminum, and can come in shapes such as Aluminum 2219 Sheet.  It is noted for its use in applications at elevated temperatures.  Aluminum 2219 Sheet is commonly used in the manufacture of structural components used in high temperature applications as well as high strength weldments.  In the annealed condition, Aluminum 2219 Sheet is readily machined.  Aluminum 2219 Sheet is more difficult to machine in any of the heat treated conditions, which is the condition in which most machining is actually done.  The use of oil base lubrication is advised for all machining operations using Aluminum 2219.

Aluminum 2219 Bar

Aluminum 2219 can come in different shapes, including Aluminum 2219 Bar.  Welding heat input affects the corrosion resistance of Aluminum 2219 Bar in an adverse manner.  Aluminum 2219 Bar may be readily formed by conventional methods.  Thus any welding should be followed by a repeat heat treatment to restore corrosion resistance. Â Aluminum 2219 Bar solution heat treatment is done at 1000 F followed by a cold water quench (T4 condition).  Hot forging may be done providing the finished product is given the aging heat treatment to restore corrosion resistance.  Hot working should be avoided unless it is feasible to give the finished product the aging heat treatment after all hot working is done.  Aluminum 2219 Bar is hardened (strengthened) by an aging heat treatment or by controlled cold working from the solution annealed condition.

Aluminum 2219 Plate

Cold working Aluminum 2219 Plate by conventional means is readily accomplished.  Solution annealing for Aluminum 2219 Plate is done at 1000 F for adequate time to allow thorough heating, followed by a cold water quench.  Aluminum 2219 is aged at 375 F, after first doing the solution anneal at 1000 F and water quench, for varying time.  Tempering is not applicable to Aluminum 2219 Plate. Â Resistance welding and inert gas welding may be used with precautions to avoid strain cracking upon cooling.  Aluminum 2219 Plate is best for a filler rod.
