The Use of 1561 Aluminum in Shipbuilding

 As ship manufacturing develops in the direction of lightweight, high-speed, and large-scale, aluminum-magnesium alloys with small density, high specific strength, and good stability have become the preferred materials to replace marine steel. In the past, 5083 aluminum alloy was mostly used in shipbuilding, but the orthopedic treatment after welding had a greater impact on the manufacturing accuracy.

1561 aluminum alloy (Russian brand) has higher strength than 5083 aluminum alloy. Using 1561 aluminum alloy as marine material will improve the quality and performance of ships. 5059 and 1561 aluminum alloys are the most high-end marine aluminum alloys and are currently recognized as the most technically difficult high-end marine aluminum alloys in the industry.

1561 aluminum alloy is a new anti-rust aluminum alloy developed based on the existing Al-Mg series marine aluminum alloy to increase the Mg and Mn content and reduce the impurity element content to meet the needs of high corrosion-resistant load-bearing components.

1561 aluminum alloy has high yield strength and small elastic modulus. It has a large rebound after multi-point forming. Small deformation can basically fully rebound after unloading. Therefore, 1561 aluminum alloy needs to be given a larger amount of springback compensation during the forming process.

When the curvature of the formed part is large, the 1561 aluminum alloy is prone to wrinkles during one-time forming. However, after adopting the multi-pass forming method, the problem of wrinkling in the center of the formed part is solved, and the forming error ± 1 mm area is increased by 80% to to 91%. The error is reduced and the forming accuracy is improved.

1561 aluminum alloy is an aluminum alloy with a high magnesium content. It is very easy to produce defects such as pores and cracks during the welding process. How to ensure that these defects do not occur in the welds during the hull construction process is a key issue to ensure production quality. The TIG deep penetration welding process is used to weld 1561 high magnesium aluminum alloy, which can significantly reduce defects such as pores and inclusions in the weld.
