Aluminium alloy 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
~ Marine & Off-shore incl. Masts,
~ Pylons, poles & masts
Alloy 5454 corresponds to the following standard designations and specifications but may not be a direct equivalent:
ISO Al Mg3MN
Al 2.7Mg 0.8Mn Cr
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 quarter hard
- H32 - Work hardened by rolling then stabilised by low-temperature heat treatment to quarter hard
Alloy 5454 is supplied in most forms but is not suitable for fine or complex extrusions:
- Treadplate/Patterened Sheet
Alloy 5454 has good weldability by some methods but Soldering and Brazing are not recommended.
Formability of Alloy 5454 is good in the softer tempers and it can be extruded.
