Aluminium alloy 5754 offers excellent corrosion resistance, particularly to seawater and industrially polluted atmospheres. It provides higher strength than alloy 5251, making it well suited for flooring, structural, and heavy-duty industrial applications. Its combination of strength, durability, and weldability makes 5754 H114 a preferred alloy for marine, transport, and industrial environments. Note: Mechanical properties listed below apply to the H114 temper.
