TEMPER TYPES
Alloy QQ-A-250/7, 5086 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
  • H34 - Stabilised - A low temperature thermal treatment or heat introduced during manufacture which stabilises the mechanical properties and relieves residual internal stress, plus usually improves ductility
  • H36 - Strain-hardened and stabilized - 3/4 hard.
