5754 O Aluminum Plate Sheet

5754-O aluminum refers to the annealed state of the 5754 aluminum alloy. Compared with other states of 5754 aluminum alloy, it has lower strength but the highest elongation. In this state, 5754 aluminum sheets are easier to form and process, suitable for applications with high requirements for formability and bending performance, such as automotive body panels.

5754-O aluminum is a corrosion-resistant aluminum alloy material designed for deep drawing, complex stamping, and other processes that require a high degree of plastic deformation.

5754-O aluminum is a non-heat-treatable wrought Al-Mg alloy, widely used in automobiles, shipbuilding, and marine industries, such as car bodies, floors, and food processing equipment.

5754 aluminum belongs to the Al-Mg series alloys (5000 series). Its core characteristics are: maintaining good corrosion resistance and weldability while possessing excellent formability.

What does "o" mean in aluminum?

"O" represents the annealed state, which is the softest condition.

Lowest strength: After annealing, all internal stresses caused by previous cold working are eliminated, making the material in the softest condition.
Highest ductility: With maximum plasticity, it is very easy to perform deep drawing, stretching, and other complex forming processes.
Strong work hardening ability: After forming in the O state, the strength can be significantly improved through subsequent cold working (such as bending, stretching).

"O" is the fully annealed state of aluminum alloy. The material undergoes the process of "heating to the recrystallization temperature (about 340-380℃) → holding for sufficient time → slow cooling."

Eliminating processing stress: Completely releases the internal stress generated during rolling, forging, and other processes, avoiding deformation and cracking during subsequent processing or use.
Reducing hardness, improving plasticity: The O state is the "soft state" of 5754 aluminum alloy, with the lowest hardness and highest elongation, suitable for stamping, bending, deep drawing, and other complex forming processes.
Performance homogenization: Ensures uniform composition and mechanical properties across the material, suitable for scenarios with high requirements for performance stability.

Precautions When Using 5754 O Aluminum Alloy

Processing Protection: O-temper material is soft and prone to scratches during stamping. Lubricant should be applied to the mold surface, or the sheet surface should be film-coated for protection.
Post-Welding Treatment: Welded joint areas may have stress. "Low-temperature annealing" is recommended to relieve stress and prevent subsequent deformation.
Corrosion Protection: Although corrosion resistance is good, long-term exposure to strong acid/alkali environments still requires protection (such as anti-corrosion coating or anodizing).
Storage Conditions: Should be stored in a dry, ventilated warehouse, avoiding contact with saltwater and chemical reagents to prevent surface oxidation or corrosion.
