What Are ABS Aluminum Alloys

In the process of the automotive industry's continuous pursuit of lightweight, high performance and environmental protection, aluminum alloy materials have gradually become the darling of automobile body manufacturing due to their excellent characteristics.

Aluminum alloys, with their many advantages such as light weight, high strength, corrosion resistance, and recyclability, not only help to improve the fuel economy of automobiles and reduce emissions, but also significantly improve the handling and safety performance of vehicles. In the field of automobile body manufacturing, the commonly used ones are 2000 series, 5000 series, 6000 series, etc.

2000 series aluminum alloy

2000 series aluminum alloy has the highest copper content and belongs to heat-treatable aluminum alloy with high strength and hardness. Its typical alloys are 2024. Due to its excellent mechanical properties, it is often used in parts of automobile bodies that are subject to greater stress, such as the body frame.

In the design of some high-end models, in order to ensure that the body can still maintain good structural integrity and safety under complex working conditions, 2024 aluminum alloy will be used to manufacture key frame components to withstand various stresses during vehicle driving.

However, this series of aluminum alloys also has certain disadvantages, such as relatively weak corrosion resistance. In some special environments, additional protective measures may be required to ensure the stability of its performance.

5000 series aluminum alloys

5000 series aluminum alloys mainly contain magnesium elements, also known as "magnesium aluminum alloys", with good formability, weldability and medium strength. Alloy 5052 and 5754 are more common. Due to its excellent comprehensive performance, it is widely used in the outer panels, doors, floors and other parts of the automobile body.

For example, the door panel of the car is made of 5000 series aluminum alloy. While ensuring sufficient strength to resist collisions and scratches in daily use, it can be processed into various complex shapes with its good formability to meet the diverse needs of automobile appearance design; its excellent weldability facilitates the connection and assembly of the door with other parts of the body.

In addition, 5000 series aluminum alloys also have good anti-sag performance, which can maintain the flatness of the body appearance to a certain extent.

6000 series aluminum alloy

6000 series aluminum alloy has high magnesium and silicon content, good corrosion and oxidation resistance, medium strength and good machinability, and typical representatives include 6061 aluminum sheet, 6063 alloy , etc.

This series of aluminum alloys is widely used in automobile body manufacturing. In addition to being used in exterior panels, doors, floors and other parts, it is also often used to manufacture automobile frame structural parts.

Taking 6061 aluminum alloy as an example, it can effectively reduce the weight of the body and improve the fuel efficiency of the vehicle while ensuring the strength of the body structure. In addition, due to its good surface treatment performance, after anodizing and other treatments, the body appearance can be made more beautiful and durable.

In some new energy vehicles, in order to increase the cruising range, a large amount of 6061 aluminum alloy is used to build the body frame, which ensures that the body has sufficient rigidity and safety while achieving lightweight.

In addition to the above-mentioned sheet aluminum alloys, high-performance cast aluminum and aluminum alloy profiles are also used in automobile body manufacturing. High-performance cast aluminum can be strengthened through heat treatment and used to manufacture some castings with complex shapes and high strength requirements, such as connectors for body frames.

As the main load-bearing components, these connectors need to have high strength to ensure the stability of the connection between the various parts of the body. Aluminum alloy profiles are often used to manufacture the skeleton structure of the body. For example, the Audi e-tron uses a large number of 6xxx series aluminum alloy profiles in the B-pillar and roof integrated parts, achieving a significant weight reduction effect while ensuring collision safety.
