5XXX series alloys, with magnesium as the major
alloying element, combine a wide range of
strength, good forming and welding
characteristics, and high resistance to general
corrosion.
Strength:
Generally increases with increasing magnesium
content, and can be further enhanced by cold
work.
Forming:
5XXX alloys are easily cold formed. Formability
being described by minimum cold bend radii.
Formability tends to increase as alloy strength
decreases.
Welding:
5XXX alloys are easily welded using GMA-W or
GTA-W processes. Weld strength equals the
minimum annealed strength (O temper) of the
welded 5XXX alloy. Welds also show good
ductility, facilitating cold forming.
Corrosion Resistance:
5XXX alloys generally have excellent corrosion
resistance, often being used in marine
applications e.g. 5083-H116.
5XXX series alloys with greater than 3.5%
magnesium (e.g. 5086 & 5083) may be
susceptible to stress corrosion cracking (SCC).
In service, limitations should be placed on the
amount of cold work and maximum permissible
operating temperature for the higher magnesium
alloys to avoid increased susceptibility to stress
corrosion cracking and intergrannular corrosion.
Such alloys should not be used at operating
temperatures >65°C. 5454 and 5754 are
manufactured with 2.7% and 3.1% magnesium
respectively and are designed for use at elevated
temperatures.
Technical Support:
For further information and advice please
contact your District Sales Office.
Availability:
5XXX alloys are most commonly available in F
(as rolled) or O/H111 (fully soft) condition,
although cold worked tempers such as H32,
H321 and H116 are also available.

With a broad combination of desirable properties 5XXX series alloys are used for many applications.
APPLICATION
Cryogenic applications: production, storage and transportation of liquid petroleum and industrial gases
Pressure vessels
Hulls and superstructures of ships such as fast ferries, naval craft and workboats
Road transport: commercial vehicles and trailers
General Engineering: mechanical components, jigs, fixtures, flat beds, base plates and general tooling.
Most 5XXX alloys are ordered to the fully annealed O condition. H321 and H116 tempers are often used in transport applications. H321 and H116
tempers are work hardened to increase strength. The most widely used 5XXX alloys are 5083, 5086 and 5754.
5754
5083 & 5086
Unlike 5083 and other alloys with more than 3.5%
magnesium, 5754 is resistant to intergrannular corrosion
and stress corrosion cracking after exposure to elevated
temperatures (above 65°C). For this reason, it is the
preferred alloy choice for applications involving prolonged
exposure to such temperatures, e.g. transportation of hot
liquids.
5083 offers the highest strength of all non heat treatable alloys, containing
approximately 4.5% magnesium, 0.7% manganese and 0.13% chromium.
5086 is less highly alloyed than 5083, containing approximately 4.0% magnesium,
0.50% manganese and 0.13% chromium. This results in lower strength but greater
ductility compared to 5083.
5086 is favoured when making fabrications which require greater formability than
offered by 5083.

Note: Radii expressed as thickness (t) are
minimum recommended for bending plates in
a standard press brake with air bend dies.
Minimum permissible radii will also vary with
design and condition of tooling.
