5083 O aluminum plate also retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys but is not recommended for use in temperatures in excess of 65°C.

 

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 4056

BS N8, 3.3547, AlMg4.5Mn0.7
 
 
TEMPER TYPES
5083 is supplied in a wide range of tempers:
  • O - Soft
  • H111 - Annealed and slightly strain-hardened (less than H11) during subsequent operations such as stretching or levelling.
  • 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
  • H36 - Strain-hardened and stabilized - 3/4 hard.
