This alloy is primarily used in areas where good formability is required, it is used in O, H112, H32, H34;
to specification ASTM B209 Tempers and is an excellent choice for large pressure vessels and certain marine fabricated products. The formability is at its best in the soft 0 temper, but also sometimes used in H32 or H34 tempers too. However the strength and corrosion resistance are not always as good as other alloys, so as always a marine structural engineer should be consulted for each application.


Aluminium alloy EN AW 5454 has s imilarities to the following standard designations and specifications ;

Alloy 5454 UNS A95454, ASTM B209

DIN AlMg3Mn, 3.3537

5454 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).
  • H22 - Work hardened by rolling then annealed to quarter hard
  • 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


5454 is supplied in plate, strip, bar, tube and sheet
  • Plate
