Aluminium 5454


Aluminium alloy 5454 has very good corrosion resistance, in particular to seawwater and general environmental conditions. Strength is medium to high and similar to ally 5754 with good strength in the temperature range 65 to 170 degrees centigrade. It has a high fatigue strength. It is not suitable for complex or fine extrusions.


This material is used for road transport body building, chemical & process plant, cyrogenics, marine & offshore, pylons, poles and masts and pressure vessels, containers & boilers.

Alloy Designations

Aluminium alloy 5454 corresponds to the following standard designations and specifications buy my not be a dirct equivalent: A5454, ISO Al Mg3MN and Al 2.7Mg 0.8Mn Cr.

Temper Types

The most common tempers for 5454 aluminium are:

  • O - Soft
  • H111 - Some work hardening imparted by shaping process but less than required for H11 temper.
  • H22 - Work hardened by rolling then annealed to quarter hard.
  • H32 - Work hardened by rolling then stabilised by low temperatire heat treatment to quarter hear.


Formability of Alloy 545 is good in the softer tempers and it can be extruded.


Alloy 5454 has good weldability by some methods but soldering and brazing are not recommended.
