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. 100 100 95 95 75 75 25 25 5 5 0 0 5xxx.ps I:\Alcoa\betetlapok\5xxx.cdr 2005. jœnius 3. 15:17:47 Color profile: Generic CMYK printer profile Composite 200 lpi at 45 degrees europeanmillproducts 100 100 95 95 75 75 5xxx series alloys technical data 25 5 25 STANDARD DIMENSIONAL AVAILABILITY Thickness (mm) 0 Alloy Temper 5251 F O H111 H112 F Width (mm) 5 Length (mm) 0 Min Max Max Max 6.35 >20 >113 20 113 103.2 3150 2978 2967* 20000 >203.2 590 2080 3150 Mill finish 5052 5454 5754 5456 5083 5086 Brushed Finish (available one or two side film coated - on request) F O H111 8 70 5083 5086 8000 2880 2978 2708* 20000 Mill finish 5754 5456 2400* 6.35 >13 >73 H32 H321 H116 13 73 203.2 1.

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.
