Aluminum 5454

Aluminum 5454 is a non-heat-treatable aluminum-magnesium alloy developed for applications requiring excellent corrosion resistance, good weldability, and reliable performance at moderately elevated temperatures. It’s particularly well suited for use in marine environments and pressure-containing applications where resistance to seawater, industrial atmospheres, and thermal exposure is critical.

Compared to other 5xxx series alloys, Aluminum 5454 offers improved resistance to stress corrosion cracking and better strength retention at elevated temperatures. These characteristics make it a preferred material for pressure vessels, tanks, piping systems, and marine structures subjected to heat and continuous service conditions.

Aluminum 5454 maintains stable mechanical properties after welding due to its solid-solution strengthening mechanism. This allows it to be used confidently in large welded assemblies and fabricated structures without significant degradation in performance.

Tech Steel & Materials supplies Aluminum 5454 in plate, bar, rod, bar, tubing and structural forms with full material traceability and certification. Value-added services such as custom cutting, processing, and specialized packaging are available to meet project requirements.
