5052 0 aluminum sheet

"5052-O aluminum plate" is a high-quality anti-rust aluminum material that is very suitable for deep and complex plastic forming. With its excellent corrosion resistance, formability, and weldability, 5052-O aluminum plate has become a core material in industries such as automotive, electronics, and shipbuilding. Its O-temper characteristics make it irreplaceable in complex cold-forming applications, while the annealing process ensures softness and stability.

• Performance: Tensile strength about 235 MPa, elongation up to 20%; not heat-treatable for strengthening, but excellent corrosion resistance.
• Applications: Suitable for aircraft fuel tanks, marine sheet-metal parts, beverage cans, and other fields requiring deep-drawing forming.
• Processing: Resistance welding is recommended to avoid cracking; annealed temper is best for stamping.

Compared with other tempers of 5052 aluminum alloy (such as H12, H14, H16, H18, H24, H32, H34), the O-temper aluminum alloy has the softest hardness and is suitable for processing various shapes and sizes.

5052: This is the alloy designation. It identifies the main alloying elements in the aluminum plate besides aluminum.

O: This is the temper code, describing the hardness, strength, and processing condition of the aluminum plate.

Aluminum plate: This refers to the product form.

Specification of 5052 O Aluminum Sheet Plate

Alloy: 5052, Temper: O (annealed, fully softened)

Alloy Grade: 5052

5052 aluminum alloy belongs to the Al-Mg series and is one of the most widely used corrosion-resistant aluminums. Its main characteristics are:

Main alloying element: Magnesium (Mg), with a content of about 2.2-2.8%. This gives it higher strength compared to pure aluminum (such as 1060) and Al-Mn series alloys (such as 3003).

Features:

• Excellent corrosion resistance: Exhibits strong resistance to corrosion in marine, chemical, and humid environments, especially outstanding seawater corrosion resistance.
• Medium strength: Significantly stronger than 1000 series pure aluminum and 3003 aluminum alloy, suitable for lightweight structural components.
• Good fatigue strength: Stable under repeated loading, suitable for components requiring anti-fatigue performance.
• Excellent formability: Easy for stretching, bending, stamping, and other cold working processes, with high-quality surface after forming.
• Good weldability: Compatible with various common welding methods (TIG, MIG, spot welding, etc.), with stable performance in welded areas.
• Outstanding surface treatment performance: Can undergo high-quality anodizing to achieve excellent appearance and corrosion-resistant surface.

Temper Code: 0 (O temper)

"0" temper, also written as "O", represents the fully annealed state.

Treatment process: The aluminum material is heated to a certain temperature and held for a period of time, then slowly cooled to completely relieve internal stresses.

Material state:

• Very soft: This is the softest state of aluminum.
• Lowest strength: Both tensile strength and yield strength are the lowest among all states.
• Excellent plasticity and ductility: Can undergo maximum cold working and complex forming without cracking.

In short, 5052-0 aluminum sheet is the "softest and most easily formable" 5052 aluminum sheet.

Comparison of 5052 O with Other Common Tempers

What is the difference between 5052-H32 and 5052 O?

• 5052-O = soft, highly formable, lower strength
• 5052-H32 = medium-hard, stronger, still formable, slightly less ductile

Temper and Treatment

5052-O (Annealed / Softened)

"O" means fully annealed, soft, and ductile.

No strain hardening; this is the softest form of 5052.

Excellent formability and corrosion resistance.

5052-H32 (Strain-Hardened + Stabilized)

"H32" means strain-hardened and stabilized.

Moderately hard; it has undergone partial cold working.

Higher strength than 5052-O but still reasonably formable.

Formability

• 5052-O: Excellent; easy to bend, roll, or shape. Ideal for deep drawing or complex forming.
• 5052-H32: Good; suitable for moderate forming, but not as flexible as O temper.

Corrosion Resistance

Both have excellent corrosion resistance, especially to salt water and marine environments. Tempering does not significantly affect corrosion resistance.

Applications

5052-O: Applications requiring high formability and corrosion resistance:

Roofing panels, siding, fuel tanks, chemical tanks

5052-H32: Applications requiring higher strength with reasonable formability:

Marine panels, automotive parts, pressure vessels, truck beds
