Aluminium 5454 has very good corrosion resistance, in particular to seawater and general environmental conditions. Strength is medium to high and similar alloy 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.
Applications 5454 is typically used in:
~ Road Transport Body-Building
~ Cemical and Process Plant
~ Pressure Vessels, Containers, Boilers
~ Cryogenics
~ Marine & Off-shore incl. Masts,
~ Pylons, poles & masts
Alloy Designations
Alloy 5454 also conforms to:
A5454
ISO Al Mg3MN
Al 2.7Mg 0.8Mn Cr
Temper Types
The most common tempers for 5454 aluminium are shown below
- O - Soft
- H111 - Some work hardening imparted by shaping processes but less than required for H11 temper
- H22 - Work hardened by rolling then annealed to quater hard
- H32 - Work hardened by rolling then stabilised by low-temperature heat treatment to quarter hard
Weldability
Alloy 5454 has good weldability by some methods but Soldering and Brazing are not recommended.
Fabrication
Formability of Alloy 5454 is good in the sofetr tempers and it can be extruded.
