Aluminium alloy 5754 offers excellent corrosion resistance, particularly in seawater and industrially polluted environments. It provides higher strength than alloy 5251, making it especially suitable for flooring and heavy-duty structural applications. The H26 temper (three-quarter hard) delivers enhanced strength and surface hardness, making it ideal where increased load-bearing capacity and wear resistance are required. Note: Mechanical properties listed below apply to the H26 temper.
Alloy 5754 is typically used in:
