Aluminium Alloy - Commercial Alloy - 5454

5454 - H22 and H32 Sheet

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
~ Cryogenics
~ Marine & Off-shore incl. Masts,
~ Pylons, poles & masts

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 quarter hard
H32 - Work hardened by rolling then stabilised by low-temperature heat treatment to quarter hard

Supplied Forms

Alloy 5454 is supplied in most forms but is not suitable for fine or complex extrusions:
