6061 marine grade aluminum

The field of marine ship construction requires the high performance of metal materials, so there are more stringent process requirements and performance standards. 6061 marine grade aluminum happens to be enough. 6061 has good processing performance and good corrosion resistance. When used in marine use, it exhibits high toughness, no deformation after processing, easy coating, and good oxidation effect.



And 6061 aluminum sheet can still maintain good operability after annealing, especially without stress corrosion cracking tendency, and its weldability and cold workability are also excellent.

Advantages of marine grade aluminum 6061

Marine grade aluminum 6061 use magnesium and silicon as the main alloying elements. These two elements enhance the corrosion resistance and physical strength of 6061, and 6061 has excellent processing performance and relatively high toughness. Let’s expand the description:

6061 has a high yield strength and elastic modulus

The yield strength and elastic modulus of materials are the most basic parameters for calculating the strength of the ship structure and determining the size of the structure. A small amount of alloying elements are added to 6061, which has medium strength after processing and also improves the elastic modulus. At this time, it is easier to weld and will not affect the corrosion resistance.


Marine-grade aluminum 6061 has excellent welding performance

Marine-grade aluminum 6061 has good weldability, and the tendency of cracks formed during welding is smaller. 6061 belongs to the material strength and corrosion resistance after welding will not decrease, as a welding ship material, it has more advantages than Al-Zn-Mg or Al-Si-Mg alloy.


6061 marine grade aluminum has excellent corrosion resistance

The substrate and welded joints of ships constructed with 6061 marine-grade aluminum are resistant to corrosion in seawater and marine environments, without stress corrosion, spalling corrosion, and intergranular corrosion.

6061 marine grade aluminum has a good cold and hot forming properties

Ships undergo cold processing (such as hemming, hemming, roll bending, stamping, etc.) and thermal processing (such as hot bending, pyrotechnics, etc.) during the construction process. 6061 marine grade aluminum is easy to process and shape, and does not produce defects such as cracks during processing. After processing, when 6061 aluminum marine use can still meet performance requirements such as strength and corrosion resistance.


The above is the introduction to the characteristics of 6061 marine grade aluminum. Of course, in addition to the shipbuilding industry, 6061 can also be used in mechanical parts, precision machining, industrial materials, and construction industries. When choosing an aluminum plate manufacturer, in addition to choosing a large, regular and well-known manufacturer, it also depends on the quality and specifications of the aluminum plate to choose from its surface and comprehensive performance.

6061 marine grade aluminum manufacturer

The selection of marine aluminum alloy materials is relatively strict, and the most used ones are 5052, 5454, 5083, 5086, 5754, 6063, 6061 aluminum sheet plates, and so on. The main states of materials are: O, H14, H112, H34, H32, H116, H117, H111, T4, T6, T651, etc. Henan Mingtai Aluminum Co., Ltd. is a large-scale manufacturer. Its 5XXX series and 6XXX series marine aluminum plates have passed the certification of China Classification Society (CCS).
