Aluminum Alloy 5083 Sheets

Aluminum alloy 5083 is a high magnesium alloy with excellent strength and corrosion resistance, commonly used in marine applications. Suffixes such as H111, H112, H116, and H3211 represent different temperature conditions for these sheets. Here's a brief description of each:

H111: This temperature indicates that the aluminum sheet or plate has been annealed, meaning it has been subjected to thermal treatment to increase its strength. In the case of H111, it is suitable for products with constant thickness, and it has the lowest strength compared to other tempers.

H112: This temper is similar to H111 but with slightly better mechanical properties. It is also suitable for products with constant thickness, and indicates that the material has been annealed.

H116: This temperament is a high-strength stress-hardening condition. This means that the aluminum has gone through a process called strain hardening or cold working, which increases its strength. H116 is particularly common in marine applications where high strength is important.

H321: This temperature indicates a stabilized product that has been strain-hardened and partially annealed. It is specifically designed for applications in which the material will be subjected to severe forming and where corrosion resistance is essential, especially in marine environments.

Alloy Composition: Aluminum alloy 5083 consists primarily of aluminum, magnesium and traces of manganese and chromium. The composition of the alloy contributes to its high strength and corrosion resistance properties.

Aluminum alloy 5083, which is renowned for its remarkable properties, is rich in aluminum (Al), magnesium (Mg), manganese (Mn) and chromium (Cr). Offering a harmonious blend of high tensile strength and exceptional corrosion resistance, this alloy finds its place in diverse industries. Different temperature conditions tailor its properties to specific applications. H111 and H112, with varying levels of cold working, meet products with minimal to moderate forming requirements. H116, a hot-rolled, tension-hardened temper, is suitable for applications demanding increased strength, especially in marine structures. H321, in a stable and partially dissolved state, meets critical manufacturing requirements, making it ideal for marine environments. With applications spanning marine, aerospace, oil and gas and structural components, aluminum alloy 5083 stands out as a versatile material, excelling in performance and reliability. Whether in shipbuilding, aerospace components, or structural frameworks, its excellent machinability, weldability, and corrosion resistance make it the preferred choice for critical applications worldwide.
