Note: Square bars and hexagonal bars use the inscribed circle diameter.
Strength and hardness: The strength of 5A05 aluminum is comparable to 5A03, and it is suitable for applications that require medium strength. It has high strength and hardness, and can maintain stable performance in various working environments.
Plasticity: In the annealed state, 5A05 aluminum has high plasticity and is easy to process and form; while in semi-cold hardening, its plasticity is moderate and can still meet certain processing requirements.
Heat treatment: It is worth noting that 5A05 aluminum cannot be strengthened by heat treatment, which means that its strength cannot be further improved by heat treatment.
Processing properties of 5A05 aluminum bar
Processing performance: 5A05 aluminum has good processing performance and can be processed into parts and components of various shapes and sizes through various forming processes.
Welding performance: In the annealed state, 5A05 aluminum has good welding performance and supports a variety of welding methods such as hydrogen atom welding, spot welding, gas welding, and argon arc welding.
Cutting performance: In the annealed state, the cutting performance of 5A05 aluminum is low, but it improves when semi-cold hardening. In addition, when manufacturing parts such as rivets, anodizing treatment is required to increase their surface hardness.

Comparison of 5A02, 5A05, and 5A06 aluminum bars
5A02, 5A05, and 5A06 are all aluminum-magnesium alloys from the 5xxx series, known for their excellent corrosion resistance, good weldability, and moderate to high strength. However, they differ slightly in mechanical performance and typical applications:
- 5A02 aluminum bar features moderate strength with excellent corrosion resistance, making it suitable for marine components, pressure vessels, and general structural use where light weight and durability are required.
- 5A05 aluminum bar offers slightly higher strength and is commonly used in larger welded structures such as railway vehicles, storage tanks, and ship hull components.
- 5A06 aluminum bar delivers the highest strength among the three, along with good toughness and processability. It is ideal for demanding aerospace, military, and structural applications that require both strength and corrosion protection.
