With the increasing popularity of energy saving and consumption reduction, car lightweighting is increasingly being valued by car companies. In the application of automotive lightweight materials, a lightweight aluminum alloy material with both mechanical and technical advantages is being sought after in the industry. Automotive aluminum can significantly reduce the weight of the vehicle while achieving the same level of quality and durability. . In addition, based on the characteristics of unlimited recycling of aluminum materials, carbon emissions can be minimized to help environmental protection and take the path of sustainable development.

Advantages of automotive aluminum


1. Weight reduction, weight reduction of key parts up to 40%


2. Applicability, high thermal conductivity and high electrical conductivity


3. Corrosion resistance, aluminum oxide layer prevents corrosion


4. Recyclability, nearly 90% of automotive aluminum can be recycled


5. Easy to shape, excellent quality, sharp shape


Application of aluminum for automobiles


Different aluminum alloys are used for different stressed parts of the car body. The lightweight of the car can be roughly divided into lightweight body, lightweight engine, lightweight chassis, and lightweight heat exchange system. The automotive aluminum produced by Mingtai Aluminum is mainly 3 series, 5 series and 6 series.


Lightweight body: 5052 aluminum plate, 5754 aluminum plate, 5182 aluminum plate, 6061 aluminum plate, 6082 aluminum plate


Lightweight chassis: 6061 aluminum plate


Lightweight engine: 5454 aluminum plate, 5754 aluminum plate


Lightweight heat exchange system: 1050 aluminum plate, 3003 aluminum plate, 3004 aluminum plate, 5052 aluminum plate, 6063 aluminum plate

Aluminum alloy is widely used in automobiles


Aluminum for automobiles is mainly divided into three forms: die-casting, extrusion and rolling. At present, die-casting parts in automobiles are mainly used for engines, wheels and other parts, extrusion parts are mainly used for seat frames, luggage racks, door beams, etc., and rolled parts are mainly used for the production of aluminum panels for bodywork. Generally speaking, the weight of the vehicle body accounts for about 30-40% of the weight of the whole vehicle. In the future, the all-aluminum body is the main development direction of automotive aluminum.


The market for automotive aluminum


Lightweight ordinary cars, speeding up the demand for aluminum. New energy vehicles have more urgent demand for aluminum alloys, and new energy vehicle production has increased rapidly. The demand for aluminum is currently mainly dependent on foreign imports. However, with the mass production and stable supply of domestic automotive aluminum products, the price competitive advantage will also be very obvious. . This will also promote the use of aluminum alloy body panels in more automobile manufacturing. Experts predict that aluminum alloys for interior trim and automotive panels will exceed 700,000 tons in 2020. The prospects for domestic automotive aluminum panels are bright. Domestic aluminum processing manufacturers should seize this development opportunity and realize the large-scale production of automotive aluminum panels as soon as possible. Lay a solid foundation for long-term development.
