5454 - Alloyed with 2.7% magnesium, 0.8% manganese and 0.12% chromium. Good formability, weldability and corrosion resistance. Often used for pressure vessels. Tensile strength between 36,000 to 47,000 psi.

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

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

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.

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.

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".

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

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

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.
