Principal Design Features		AL 2219 is an age-hardenable copper containing alloy of aluminum. It is noted for applications at elevated temperatures.

Applications		Commonly used in the manufacture of structural components used in high temperature applications as well as high strength weldments.

Machinability		In the annealed condition this alloy is readily machined. It is more difficult to machine in any of the heat treated conditions, which is the condition in which most machining is actually done. Use of oil base lubrication is advised for all machining operations.

Forming		The alloy may be readily formed by conventional methods. However there are precautions in regard to hot forming - see "Hot Working".

Welding		Welding heat input affects the corrosion resistance of this alloy in an adverse manner. Thus any welding should be followed by a repeat heat treatment to restore corrosion resistance. Resistance welding and inert gas welding may be used with precautions to avoid strain cracking upon cooling. Alloy 2319 is best for a filler rod.

Heat Treatment		Solution heat treatment is done at 1000 F followed by a cold water quench (T4 condition).

Forging		Hot forging may be done providing the finished product is given the aging heat treatment to restore corrosion resistance.

Hot Working		Hot working should be avoided unless it is feasible to give the finished product the aging heat treatment after all hot working is done. Otherwise the corrosion resistance will be adversely affected.

Cold Working		Cold working by conventional means is readily accomplished.

Annealing		Solution annealing is done at 1000 F for adequate time to allow thorough heating, followed by a cold water quench.

Aging		The alloy is aged at 375 F, after first doing the solution anneal at 1000 F and water quench, for varying time. For product forms such as forgings the 375 F aging is for 18 hours and for sheet, or plate (up to 2" thick) it is 375 F for 36 hours followed by air cooling in each instance.

Tempering		Not applicable to this alloy.

Hardening		This alloy is hardened (strengthened) by an aging heat treatment or by controlled cold working from the solution annealed condition. See "Heat Treatment" and "Aging".

Other Physical Props		Electrical conductivity 30% that of copper.
