    Common States and Hardnesses of 5052 Aluminum Sheet

    5052 aluminum sheet is available in various tempers and hardness levels to suit different applications and processing requirements. The temper of an aluminum alloy sheet is determined by the heat treatment and mechanical processing it undergoes. Common tempers and their associated hardness levels for 5052 aluminum sheet metal include:

    1. O Temper (Annealed): This is the softest temper for 5052 aluminum. It is fully annealed, which means it has undergone a process of heating and slow cooling to remove internal stresses. In this temper, 5052 aluminum is very soft and easy to work with. It typically has a low hardness.
    2. H32 and H34 Tempers: These are strain-hardened tempers and are some of the most commonly used for 5052 aluminum. H32 is a strain-hardened version of the O temper, while H34 is even harder. These tempers provide good strength and are suitable for many general-purpose applications.
    3. H36 and H38 Tempers: These are also strain-hardened tempers that provide higher levels of hardness and strength compared to H32 and H34. H36 and H38 are used in applications where greater strength and resistance to deformation are required.
    4. H116 and H321 Tempers: These tempers are designed specifically for marine applications, where corrosion resistance is critical. H116 and H321 are strain-hardened and have enhanced corrosion resistance and strength compared to other tempers.
    5. Other Custom Tempers: Depending on the specific requirements of a project, custom tempers can be developed to achieve the desired mechanical properties. These may include variations in hardness and strength to meet unique applications

      • Others (each): 0.05% max
      • Others (total): 0.15% max

      Please note that these are typical ranges, and the exact composition may vary among different suppliers and specific alloy versions.

      Mechanical Properties (for H32 Temper, typical values):

      • Tensile Strength: 31,000 - 41,000 psi (214 - 283 MPa)
      • Yield Strength: 22,000 - 30,000 psi (152 - 207 MPa)
      • Elongation: 12% - 20%
      • Hardness (Brinell): 60 - 73 HB
      • Hardness (Rockwell B): 40 - 48 HRB

      The mechanical properties of 5052 aluminum sheets can significantly change with different temper conditions. For example, the properties will be different for the O (annealed), H32, H34, H36, H38, H116, and H321 tempers. The values mentioned above are typical for the H32 temper, which is one of the most common and versatile temper conditions for 5052 aluminum sheets. The O temper will have lower strength and higher elongation, while the H36, H38, H116, and H321 tempers will have higher strength and varying levels of hardness and elongation.

      It's important to refer to the specific data provided by the manufacturer or supplier to obtain precise information on the chemical composition and mechanical properties of the 5052 aluminum sheets you plan to use, as these values can vary among different product specifications and sources.

      Comparison of 5052-H32 and 5052-H34

      5052-H32 and 5052-H34 are two common temper conditions for 5052 aluminum alloy machining. They are both strain-hardened tempers and share many similarities, but there are some differences between them. Here's a comparison of 5052-H32 and 5052-H34:

      1. Strength: Both 5052-H32 and 5052-H34 are strain-hardened tempers, and as a result, they have similar levels of strength. The difference in strength between the two is generally minimal. The "H32" and "H34" designations indicate that they have been strain-hardened to a specific level to achieve the desired strength characteristics.
      2. Formability: Both tempers have good formability, making them suitable for a wide range of applications that require bending, shaping, and forming. They are often used in the fabrication of various structural and non-structural components.
      3. Corrosion Resistance: 5052 aluminum is known for its excellent corrosion resistance, and this property is not significantly affected by the difference between H32 and H34 tempers. They both maintain the alloy's corrosion resistance.
      4. Applications: Both 5052-H32 and 5052-H34 are commonly used in similar applications, such as the construction of boat hulls, automotive panels, and various components where a balance of strength and formability is required.
