5454 Alloy

Main alloying elements:

Magnesium (Mg): approx. 2.4% - 3.0%. Magnesium is the primary strengthening element, significantly improving aluminum strength while maintaining good corrosion resistance and weldability.
Manganese (Mn): approx. 0.5% - 1.0%. Manganese provides additional solid solution strengthening and improves the alloy's recrystallization structure.
Chromium (Cr): added in small amounts, helps enhance resistance to stress corrosion cracking.

Main features:

Medium strength: Strength between 5052 and 5083/5086.
Excellent corrosion resistance: Especially resistant to chloride-induced stress corrosion cracking in marine and chemical industrial environments.
Good weldability: Can be welded using multiple methods, with high post-weld strength recovery.
Stable performance at elevated temperatures: Compared to higher Mg 5xxx alloys (e.g., 5083), 5454 is less prone to sensitization at higher temperatures.

H34 (Cold Work Hardened Temper)

"H" denotes a cold-work hardened temper, where material strength is increased through cold working processes such as rolling or stretching. "H34" is a specific subdivision.

H3X: Indicates the material has been cold-worked and stabilized. Stabilization treatment (usually low-temperature heating) stabilizes the material’s properties, preventing changes caused by natural aging at room temperature.

The first digit 3: Represents the final mechanical properties lying between H32 and H36.

The second digit 4: Specifically defines the strength level of the material. H34 indicates that the material has been cold-work hardened to a specific standard strength range.

H34 means that this 5454 aluminum plate/coil has been hardened to a specific strength level via cold rolling or similar processes before leaving the factory, and has undergone stabilization treatment, resulting in stable and predictable performance.

5454 H34 Properties

Strength: Medium-high, higher than 5454-O (annealed) and 5052-H32, approximately 20% stronger than 5052 aluminum.
Workability: Good formability, but slightly lower than O temper.
Excellent corrosion resistance: Outstanding stress corrosion cracking resistance, especially in marine and chemical environments, superior to alloys like 5154.
Excellent weldability: Minimal strength loss after welding, maintains good weld strength, suitable for TIG, MIG, and resistance welding processes.
High plasticity: Good formability, easy to process into various shapes.
Cold work hardened: H34 temper indicates strength is achieved via cold working.
Thermal stability: Good performance at low temperatures, suitable for cryogenic applications.

5454 H34 Corrosion Resistance

Excellent corrosion resistance: Outstanding resistance to pitting and exfoliation corrosion in harsh marine environments, chlorides, acid rain, and industrial atmospheres; stress corrosion cracking resistance significantly better than 5154 alloy.
Wide application range: With excellent corrosion resistance and strength, it is ideal for manufacturing ship decks, marine engineering structures, and chemical containers.
Excellent surface treatment compatibility: 5454 aluminum can undergo anodizing or plating, further improving corrosion resistance, wear resistance, and providing decorative appearance to extend service life.
