Marine grade 5059 aluminum plate is a specialized alloy designed for marine applications and is known for its exceptional corrosion resistance, high strength and excellent weldability.

5059 marine aluminum plate belongs to the 5 series aluminum-magnesium alloy and is commonly used in marine engineering. 5059 aluminum alloy can be used from ships of tens or hundreds of tons to ships and cruise ships of tens of thousands of tons.

Marine grade 5059 aluminum plate

The performance of 5059 alloy is better than that of 5083 alloy. However, due to its higher magnesium content, its pressure processing and forming capabilities are slightly inferior to those of 5083 alloy. Generally speaking, 5059 has better mechanical properties and corrosion resistance than 5083 marine grade aluminum and can be used as a replacement for 5083.

Why choose 5059 aluminum plate for ship plate?

Using 5059 aluminum alloy plates instead of conventional steel plates as the hull material can not only reduce the weight of the hull, but also make up for the problem of steel plates failing due to corrosion during use.
