Principal Design Features
|
|
This is an alloy of aluminum and magnesium with good strength. It does not respond to hardening by heat treatment. The alloy is good for structural use because of its good weldability.
|
|
|
Applications
|
|
Commonly used in the manufacture of high strength welded structures, pressure vessels, marine applications, and in storage tanks.
|
|
|
Machinability
|
|
Generally difficult to machine. Carbide tooling and oil lubricants should be used.
|
|
|
Forming
|
|
Forming of this alloy is more difficult than for other aluminum alloys. It requires generous bend radius and should not be severely cold worked. See "Cold Working".
|
|
|
Welding
|
|
Arc welding is best for this alloy and this makes it useful for structural applications. Gas welding may be used, but results are less favorable than for arc welding.
|
|
|
Heat Treatment
|
|
Not hardenable by heat treatment. See "Annealing".
|
|
|
Hot Working
|
|
Hot working of this alloy may be done at 425 F. This will avoid imparting high stress into heavily cold worked shapes.
|
|
|
Cold Working
|
|
The alloy may be readily cold worked. However severe cold working (over 20 % reduction) should be avoided as this may make the part subject to stress corrosion cracking in application where temperatures can reach 150 F.
|
|
|
Annealing
|
|
Anneal at 650 F and air cool.
|
|
|
Aging
|
|
Not applicable to this alloy.
|
|
|
Tempering
|
|
Not applicable.
|
|
|
Hardening
|
|
Hardens due to cold working only and the amount of cold work should be limited. See "Cold Working".
|
|
|
Other Physical Props
|
|
Electrical conductivity is 32% of copper.
|
|
|
Other Mechanical Props
|
|
Shear strengths for various tempers are: O temper, 28 ksi. H321, 30 ksi. H311, 28 ksi
