Aluminum 5083 Sheet for Ship Building

Aluminum alloys are widely used in high-speed shipbuilding industry because of their low density, high specific strength, high electrical and thermal conductivity, and no low-temperature brittleness. The main purpose is to reduce the weight of ships and increase the speed. Because of its non-magnetic properties, it can avoid magnetic mine attacks and improve instrument accuracy, which has been one of the widely concerned military materials.

Al-Mg aluminum plates, also called rust-proof aluminum sheets are of good corrosion resistance and weldability, which have become the most important aluminum alloys for the manufacture of ship hulls and stress-bearing components.

The hull and other components of aluminum alloy ships are usually manufactured by plastic forming and welding. Due to the large thermal conductivity and coefficient of linear expansion of aluminum alloys, it is required to strictly control the assembly gap of aluminum alloy processed and formed parts during welding, which requires that the edges of aluminum alloy components are not warped after forming.

However, the large rust-proof aluminum alloy ship plate for ships often shows anisotropy during the processing and forming process after blanking, and irregular warping of the formed parts occurs, which is difficult to meet the dimensional accuracy requirements, which seriously affects the subsequent welding process of the ship plate and the overall performance of the ship.

Therefore, how to eliminate or minimize the anisotropy problem in the process of aluminum alloy processing and forming to improve its processing and forming performance and dimensional accuracy after forming, has become an important problem to be solved urgently. Take aluminum 5083 plate for example.

The anisotropy of mechanical properties of 5083 aluminum sheet in different thicknesses is different. Among them, the in-plane anisotropy index IPA of the mechanical properties of the surface layer is the largest, while the in-plane anisotropy index IPA of the mechanical properties of other thicknesses is similar.

Among the three parameters of yield strength, tensile strength and elongation, the difference in IPA value of yield strength is the largest, and the IPA index of yield strength of the outermost layer reaches 24.04%. The tensile fractures of 5083 aluminum plate in different layers and directions are typical dimple fractures.
