Aluminum 5454

Aging Procedure

Not applicable to this alloy.

Annealing Procedure

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

Applications

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

Cold Workability

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..

Forgeability

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

Formability

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.

Hardening Procedure

Hardens by means of cold working only.

Heat Treatability

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

Hot Workability

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

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.

Other Mechanical Properties

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

Other Physical Properties

Electrical conductivity 32% of copper.

Principle 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.

Tempering Procedure

Not applicable.

Weldability

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.
