5000 Series Aluminum Sheet for Marine Applications

2015-12-22

Aluminum sheet for marine applications can be divided into wrought and cast aluminum alloy according to the different technologies. Aluminum alloy for marine applications must have high strength and good resistance to correction. Besides, marine applications also demand weldability and other special requirements. 5000 series aluminum sheet belongs to Al-Mg-Zn alloy, and it can satisfy the demands above. Thus, 5000 series aluminum sheets are high suitable for marine applications.

5000 Series Aluminum Sheet for Marine Applications

 

6000 series aluminum sheet can be corrupted in the sea water, so it is mainly used in the upper parts of ships. 7000 series aluminum sheet has bad resistance to correction, so the applications are limited. In comprehensive view, the application of 5000 series aluminum sheet is pretty broad. What’s more, 5000 series aluminum sheet has a good prospect. 5000 series aluminum sheet for marine application mainly include 5083 aluminum sheet, 5086 aluminum sheet as well as 5456 aluminum sheet. First, let us take Mingtai Aluminum Industry Co., Ltd as example to analysis the characteristics of 5000 series aluminum sheet.

5000 series aluminum sheet of Mingtai Al. has many tempers, such as O, H111, H112, H116, H321, etc. 5000 series aluminum sheet contents 0.4% of max Si, 0.1% of max Cu, 4.0%- 4.9% of Mg, 0.25% of max Zn, 0.4%- 1.0% of Mn, 0.15% of max Ti, 0.05%- 0.25% of Cr, 0.4% of max Fe, and the balance is Al. Because of the contents above, 5000 series aluminum sheet has middle strength, good resistance to correction and fatigue, as well as formability. These characteristics make 5000 series aluminum sheet high suitable for marine application. Other aluminum alloys, such as 5052, 5086, 5454, 5456, are applied to marine as pressure vessels, tubes, ship body, deck, etc.

Generally speaking, the thickness of aluminum sheet is decided by the body structure, specifications and the parts that it used in. If consider the lightweight in marine, thin aluminum sheet is more appropriate. In other ways, the corruption depth along with time should also be considered, so thickness from 1.6mm to 30mm of 5000 series aluminum sheet is generally adopted. However, there are also specific thickness or with of aluminum sheet. The deck of ship prefers aluminum tread plate for its anti-slippery.

Seeing the development of aluminum sheet for marine application, many aluminum manufacturers begin to research 6000 series and 5000 series aluminum sheet for marine application. Mingtai Al. has 18 years in aluminum deep processing industry. And some products, such as 5083, 5086, 5454, etc., of Mingtai Al. has been certificated to CSS and NVS GL. This means Mingtai Al. has the license in 5000 series aluminum sheet for marine application both domestic and broad. This not only gain more development space for Mingtai Al., but also set a positive example for manufacturers in domestic.
