aluminium profile exhibition | Aluminium alloy battery tray is widely used in the manufacture of new energy vehicles

With the high-quality and rapid development of the new energy automobile industry in the past two years, the battery pack technology has also been hailed by the industry as the fifth major technology in automobile manufacturing. As an important part of the battery pack, the design, material selection and manufacturing process of the new energy battery tray have attracted tremendous attention from the industry chain!

According to aluminium profile exhibition, the increase of production scale of new energy automobile industry is an inevitable trend, and its production line must achieve automation, flexibility, intelligence and integration. Battery tray scale production is also a general trend, requiring battery tray manufacturers to quickly establish automated production lines, and make battery tray line production has become a trend!

Aluminium alloy is one of the commonly used materials for battery trays, which has the advantages of light weight, high strength and good corrosion resistance. Therefore, it is widely used in the manufacture of battery trays. Commonly used aluminium alloy materials include 5×××× system (Al-Mg system), 6×××× system (Al-Mg-Si system) and so on. Among them, 6061T6 aluminium alloy is one of the more common aluminium alloy materials for battery trays, which has good strength and stiffness, as well as good machining performance and welding performance.

There are two main processing routes of aluminium alloy battery tray currently: one is extrusion profile welding, which is preferred by more vehicle manufacturers. The products boasts the advantage of good structural strength. The other is a one-piece die casting + mask welding, the advantage of this scheme is higher efficiency.

The aluminium alloy material commonly used for battery trays has the following advantages:

Lightweight: Aluminium alloy is a lightweight material and has a lighter weight compared to steel, which helps to reduce the overall total weight of the entire battery system. Automakers pursue the goal of lightweighting because it improves fuel efficiency, extends battery life, and improves vehicle performance.

High reliability: Aluminium alloys have good corrosion and weathering resistance, allowing them to maintain stable performance in a variety of environments. In addition, aluminium alloys have good machinability and weldability, which can meet various requirements in the manufacturing process of battery trays.

Feature-rich: Aluminium alloy has good thermal and electrical conductivity, which can meet the requirements of battery trays in terms of heat dissipation and electricity. In addition, aluminium alloy has good plasticity and processing performance, which can be processed and customized according to different design requirements.

Good economic value: the price of aluminium alloy is relatively reasonable, and at the same time, it has a long service life and low maintenance costs, which can save costs for enterprises.

Aluminium alloy, as a kind of battery tray material, has the advantages of light weight, high reliability, rich functions and good economy. Therefore, it is widely used in the manufacture of new energy vehicles.
