5083 aluminum plate retains good formability due to excellent ductility. It is highly suitable for welding and can be hardened by cold work. Because Alloy 5083 exhibits excellent resistance to general corrosion, it is used in marine, aerospace applications.
ALLOY DESIGNATIONS
Aluminium alloy QQ-A-250/6, 5083 has s imilarities to the following standard designations and specifications ;
Alloy 5083, UNS A95083, ASTM B209
ISO AlMg4.5Mn, AMS 4059

TEMPER TYPES
Alloy QQ-A-250/6, 5083 is supplied in a wide range of tempers:
- O - Soft
- H112 - Applies to alloys that acquire some temper from shaping processes which do not have special control over the amount of strain-hardening or thermal treatment, but for which there are mechanical property limits.
- H116 - Applies to aluminium-magnesium alloys with a magnesium content of 4% or more and for which mechanical property limits and exfoliation corrosion resistance are specified.
- H32 - Work hardened by rolling then stabilised by low-temperature heat treatment to quarter hard
- H321 - Applies to alloys which are strain-hardened less than the amount required for a controlled H32 temper
