Properties of 5754 Aluminum Plate For Sale

5754 aluminum plate for sale belongs to the aluminum-magnesium alloy (5000 series aluminum alloy), a widely used medium-strength alloy within the 5000 series. Its core characteristics are excellent corrosion resistance, good formability, and weldability, while also maintaining a certain level of mechanical strength. 5754 aluminum plate is widely used in ships, automobiles, pressure vessels, architectural decoration and other fields.

1. 1. Physical Properties

– Density (20°C): 2.68 g/cm³, approximately one-third that of steel, offering significant lightweight advantages.

– Melting point: 600-615°C, lower than pure aluminum (660°C), requiring temperature control during welding.

– Thermal conductivity (20°C): 125 W/(m·K), approximately 60% of pure aluminum, provides excellent heat dissipation, making it suitable for heat-dissipating components.

– Electrical conductivity (20°C): 28% IACS, offering moderate conductivity, suitable for components with low conductivity requirements.

– Linear expansion coefficient (20-100°C): 23.8 ×10⁻⁶/°C, similar to most 5000 series aluminum alloys, allowing for controlled deformation during temperature fluctuations.

2. 2. Corrosion Resistance (Core Advantage)

The corrosion resistance of 5754 aluminum plate is one of its core competitive advantages, making it particularly suitable for humid, marine, or industrial corrosive environments. Specifically, it demonstrates the following:

– Atmospheric corrosion resistance: At room temperature, in dry or humid atmospheres, the surface readily forms a dense, The Al₂O₃ oxide film prevents further corrosion, resulting in no noticeable rust even after long-term exposure.

– Seawater Corrosion Resistance: The judicious addition of magnesium improves the alloy’s tolerance to chloride ions (Cl⁻), surpassing most aluminum alloys (such as 2000 series and 6000 series). It can be used for ship hulls and offshore platform components.

– Stress Corrosion Cracking (SCC) Resistance: By controlling the Cr and Mn content and refining the grain size, the risk of stress cracking in corrosive environments after cold working is effectively reduced.

3. 3. Processability

– Formability: Excellent plasticity in both the O and H111 tempers allows for complex forming processes such as deep drawing, bending, and stamping. The minimum bend radius (through the thickness) can be as low as 1.5 times the plate thickness.

– Weldability: Compatible with common welding methods such as TIG and MIG welding, the weld joint strength can reach 80%-90% of the parent material, with no significant reduction in corrosion resistance after welding, eliminating the need for complex post-weld treatment.

– Machinability: Moderate machinability requires the use of specialized aluminum alloy tools to avoid tool sticking. After cold working, annealing (340-380°C for 1-2 hours) restores plasticity, facilitating subsequent processing.
