Marine Grade Aluminum VS Aluminum

 Compared with common aluminum alloys, the marine grade aluminum has better corrosion resistance. Al-Mg alloy is the most widely used marine grade aluminum, which has lower density than common aluminum, excellent resistance to marine climate and seawater corrosion, weldability and polishability, and excellent plasticity (Mg≤5% ), as well as good seismic performance, and higher fatigue strength than tat of duralumin.

In the chemical composition of aluminum-magnesium alloys used in marine engineering, the maximum magnesium content of 5052 alloy with low magnesium content is only 2.8%, and the content of 5083 alloy with the highest magnesium content is 4.9%. Although the strength of aluminum alloy increase due to the increase of Mg content, the plasticity and corrosion resistance decrease significantly, especially for alloys with Mg>6%.

Deformed aluminum alloys used in marine engineering include 5052 (5A02), 5252, 5154, 5454, 5754, 5083, 5086, 5059,etc. Among them, the magnesium content of the 5052 alloy is the lowest, the second group is 5154, 5454 and 5754 alloys, the magnesium content of the 5083 alloy is moderately high, 5059 aluminum has the highest magnesium content.

5059 aluminum plate is a 5xxx Al-Mg aluminum alloy with good corrosion resistance and tensile strength. It has excellent overall performance and is currently recognized as the most technically difficult high-end marine aluminum alloy, which is widely used in ships, oil tankers and other fields.

A new generation of marine engineering deformed aluminum alloy 5059 was developed in 1999 by Crus Aluminum Company (now Aleris Aluminum Company) and registered with the American Aluminum Association (AA). It is an excellent marine engineering aluminum alloy. The alloy has been used in the manufacture of cruise ships and various ships that can carry 7,000 passengers, as well as LNG ship.

Compared with the traditional 5083 alloy, the impurity Si, Fe, and Mn contents of 5059 aluminum are slightly higher, and the average content of Mg is 24% higher than that of the 5083 alloy. Zn is an impurity in 5083 alloy, but it is a trace alloying element in 5059 alloy, and 5059 alloy also contains 0.05% Zr~0.25% Zr.

Due to these differences in composition, the properties of aluminum 5059 are overall better than those of alloy 5083, but but due to its high magnesium content, its press working and forming properties are slightly inferior. Welcome to leave message below to inquire what you need.

Aluminum 5059 for Fuel Tank and Semi Truck

 Aluminum 5059 is a 5xxx aluminum tanker plate, which has high strength, high plasticity and corrosion resistance, good weldability, and low crack tendency. With its own unique advantages, it is widely used in special tank cars for dangerous goods such as petrochemicals.

The wide application of aluminum alloys like 5059 aluminum sheet in commercial vehicles, especially in oil tankers, has accelerated the pace of commercial vehicles in Europe and North America. Except for the vehicle for a few special chemicals, almost all tanks in Europe and the United States are made of aluminum plate, with a market share of more than 90%.

The oil tankers is a common transportation vehicles. In order to prevent the body from rusting, the choice of materials is more important. In order to ensure the normal operation of the tanker body, the chosen material is necessary to be of light weight, low density and strong corrosion resistance as far as possible. 5059 aluminum plate for oil tankers is such a choice.

In addition to oil tankers, 5059 aluminum plate is also used to make different types of semi trucks. An aluminum alloy semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor.

The use of 5059 aluminum tanker plate can effectively realize the overall lightweight of the vehicle, which improves the carrying performance and improves the transportation efficiency. At the same time, a lighter tank body contributes to improving fuel economy and reducing emissions.
