Principal Design Features		AL 5454 is a non-heat treatable alloy of aluminum and magnesium. It is a moderate strength alloy that may be hardened (strengthened) by cold working.

Applications		Commonly used in the manufacture of welded structures, pressure vessels, and in marine service.

Machinability		The machinability of Al 5454 is fair to poor. It is best to do machining operations with the alloy in the H-34 temper condition. Use of oil lubricants is recommended, except that very light cuts may be done dry.

Forming		This alloy does posses good hot working and cold working characteristics. It may be readily cold worked in any of the temper, or annealed, conditions.

Welding		All of the commercial welding methods will work satisfactorily with AL 5454. The TIG or MIG process, with AL 5554 or 5356 filler rod, works especially well.

Heat Treatment		This alloy is not heat treatable, except for annealing to relieve cold working - see "Annealing".

Forging		This alloy may be hot forged, although no temperature range data is available. Consult the alloy supplier.

Hot Working		Hot working may be accomplished in the temperature range of 700 to 400 F.

Cold Working		Cold working is easily accomplished with this alloy by conventional methods. It may be cold worked satisfactorily in either the annealed condition or any of the H-32, H-34, H-111 tempers..

Annealing		Annealing, if necessary to relieve cold working stress, may be done at 650 F, allowing sufficient time for thorough heating, followed by air cooling.

Aging		Not applicable to this alloy.

Tempering		Not applicable.

Hardening		Hardens by means of cold working only.

Other Physical Props		Electrical conductivity 32% of copper.

Other Mechanical Props		Shear strength varies slightly from 23 ksi in the annealed condition to 26 ksi in the H-34 temper.
