ISO AlMg5Mn1AMS QQ-A-250/9

 
 
 
TEMPER TYPES
5456 is supplied in a wide range of tempers:
  • O - Soft
  • H112 - Slightly strain-hardened from working at an elevated temperature from a limited amount of cold work (mechanical property limits specified).
  • 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 - Strain hardened to an amount less than required for a controlled H32 temper.
