Marine Grade Aluminum 5052 5083

Aluminum 5052 was developed in the United States in the 1930s. 5052 alloy is a deformed alloy that belongs to the 5000 series aluminum. It is often called aluminum-magnesium alloy. Because magnesium is the main alloying element in this alloy after aluminum.

Marine grade aluminum 5052 is mainly composed of aluminum, magnesium and a small amount of chromium, and has high corrosion resistance and weldability. The hardness of 5052 aluminum alloy is relatively low, usually with a Brinell hardness of around 60 in hardness tests. 5052 aluminum plates are generally in H112, H24, and H32 tempers.

5052-h32 represents an annealing process that accounts for a large proportion of the entire use. This annealing temperature is generally direct annealing at 420-475 degrees Celsius, which has the advantages of high temperature resistance, corrosion resistance, and oxidation resistance.

5083 aluminum plate, which belongs to the 5 series aluminum-magnesium alloy, is currently widely used on ships and yachts. Most of the medium-thick aluminum plates are used. The commonly used are H111, H112, H116 and H321. It is an aluminum alloy material commonly used by domestic and foreign shipbuilding companies.

The maximum magnesium content (mass fraction) of 5052 aluminum alloy with low magnesium content is only 2.8%, and the maximum magnesium content of 5083 aluminum alloy with the highest magnesium content is 4.9%.

Although the strength properties of the alloy increase due to the increase in magnesium content, the plasticity and corrosion resistance decrease significantly. Especially for aluminum alloys with w (Mg) > 6%, the process plasticity decreases particularly strongly.

Although 5052 aluminum is easier to process and form, marine grade aluminum 5083 can provide approximately 1.5 times the tensile and yield strength. When other conditions such as thickness are the same, a boat made of 5083 aluminum alloy can withstand greater pressure than a boat made of 5052 aluminum alloy when hit without breaking or deforming.

5052 aluminum alloy is suitable for the manufacture of economical aluminum alloy boats. The aluminum plate specifications used in this aluminum alloy boat are 2*2000*9000mm. Ocean yachts require 5083 aluminum plates. In shipbuilding, 5083 aluminum plates are often used to process multiple parts such as hulls, operating tables, and decks.
