What Are The Uses of 6061 Aluminum Marine
In the field of shipbuilding, the selection of materials is crucial. Aluminium marine alloys, especially marine grade aluminum 6061, occupy an important position in the shipbuilding industry with their unique properties and advantages.
6061 aluminum composition
Marine 6061 aluminum alloy must meet a series of strict standards. In terms of chemical composition, aluminum (Al) is the remainder, silicon (Si) content is 0.40 - 0.8, iron (Fe) ≤0.7, magnesium (Mg) is 0.8 - 1.2, chromium (Cr) is 0.04 - 0.35, etc. The precise control of the content of each element is the basis for ensuring the performance of the alloy. In terms of mechanical properties, the tensile strength σb (MPa) ≥ 180, the yield strength σ0.2 (MPa) ≥ 110, and the Brinell hardness HB is 95 - 100. These indicators ensure that the 6061 aluminum alloy can withstand the corresponding external forces in ship applications.
6061 Aluminum performance characteristics
Medium strength: It has good strength performance, with a yield strength of ≥205MPa and a tensile strength of ≥245MPa. It can withstand various stresses during the operation of the ship, whether it is the water pressure borne by the hull structure or the impact of wind and waves during navigation.
Good corrosion resistance: In the harsh environment of high salinity and high humidity in the ocean, it can withstand corrosion from various acids and alkalis. A dense aluminum oxide film will form on its surface, and combined with anodizing technology, it greatly enhances its resistance to seawater erosion and extends the service life of the ship.
Good weldability: It is easy to weld and the joint performance after welding is good, which can meet the welding requirements of complex structures in ship construction, facilitate the connection of different parts into a complete hull structure, and reduce the difficulty and cost of construction.
Good processing performance: It has good cutting performance, is easy to perform processing operations such as extrusion and forging, and can be processed into parts of various shapes and specifications according to ship design requirements to meet diverse design requirements.
Applications
Hull structural parts: It is used to manufacture key parts such as the frame, side plates, and decks of the hull. Its strength and corrosion resistance ensure the stability of the hull structure, reduce the weight of the hull, improve the navigation performance of the ship, and reduce fuel consumption.
Marine accessories and hardware: The good processing performance of 6061 aluminum alloy enables it to be easily processed into various exquisite accessories such as ship door and window frames, railings, handles, etc. Its corrosion resistance ensures that these accessories can be used for a long time in the marine environment without being damaged by corrosion.
Internal facilities: 6061 aluminum alloy is also often used in some decorative materials and furniture frames inside the ship. Its beautiful anodizing effect and good processing performance can create a comfortable and beautiful internal environment.
Different forms
Aluminum plate: It is a common form in shipbuilding and can be used to manufacture large-area parts of the hull, such as side plates, decks, etc., and is processed and formed by cutting, welding and other processes.
Extruded profiles: According to the specific needs of shipbuilding, profiles extruded into various shapes, such as special-shaped pipes for hull frames, which can better meet structural design requirements and improve material utilization.
Forgings: For some key parts that are subject to greater stress, such as certain connecting parts, forgings are made through forging processes to obtain higher strength and better performance. Welcome to learn more about 6061 aluminum marine use from us.
