What Are Aluminum Alloy Grades

Publish: Modify: Jun 04, 2024Author: From:  Haomei

Among such many aluminum alloy grades, marine 5086 and 3003 aluminium sheet are very common, which are widely used in automobile and ship building like ship hull and batery shell.

There are 8 series aluminum plates. The main aluminum alloy grades are 1060, 1100, 3003, 3004, 3105, 5052, 5083, 5086, 6061, 6082, 8011, etc. Today let’s first have a knowledge of two widely used aluminum sheets: 3003 aluminium sheet and 5086 aluminum plate.

3003 aluminum is a wrought alloy that contains only 4% alloying elements. 3xxx series aluminum alloys are usually formed by cold working/work hardening. 3003 aluminum sheets are often used with the thickness of 0.6 mm, 0.7 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, and 4 mm.

The tensile strength of 3003 aluminum alloy is 185 MPa (or 27,000 Psi). The shear strength of 3003 aluminum alloy is 110 Mpa (or 16,000 Psi). For 3003 aluminum, its shear modulus rating is 25 GPa (3630 ksi).

3003 aluminum alloy has the advantages of low density, soft material and easy overall stretching of power battery aluminum shells, and has been used by many companies for battery shells. In order to increase the driving range, new energy electric vehicles require a large number of lithium battery combination modules, each of which is composed of several battery boxes.

In this way, the weight of each battery box has a great influence on the weight of the entire battery module. In order to reduce the weight of the battery, it is inevitable to use 3003 aluminum alloy to make the battery shell.

Due to excellent corrosion resistance and weldability, coupled with high strength, marine grade aluminum alloy plates are designed for welded structures that require maximum joint strength and efficiency. Marine 5086 aluminum plate shows very good results when welded, retaining most of its strength. This factor, along with its corrosion resistance in seawater, makes it a very popular choice in the marine industry. 5086 aluminum plate is widely used in ship hulls and ship gangways.

5086 aluminum alloy can be heat treated in various states, with high mechanical properties and hardness. Generally speaking, the commonly used tempers of 5086 aluminum plates are O, H111, H112, H116, and H321. The hardness of 5086 aluminum alloy is slightly higher than that of other ordinary aluminum alloys, about 60~70HB.

An open wagon is a type of railway freight car. It is characterized by being coverless and having four side panels, two of which have openable side doors to facilitate unloading of goods. 5086 aluminum sheet has a small specific gravity. It can be used to manufacture open wagons for coal transportation to reduce the vehicle's weight.

Pressure vessels refer to closed equipment used to contain gas or liquid and bear a certain pressure. The manufacturing material of pressure vessels should consider the chemical composition, mechanical properties, physical properties, process performance and compatibility with the medium, including the weldability, operating temperature range, and pressure tolerance of the material. 5086 aluminum plate meets the material selection requirements of pressure vessels.
