Introduction of vehicle models featuring aluminum alloy body designs

The Audi R8 features an all-aluminum body design. The high-performance composite material used in the R8's body is known as Audi Space Frame (ASF). With a total weight of only 210 kilograms, it is less than half the weight of a steel frame, yet it offers excellent strength and impact resistance. The composition of the entire vehicle body consists of 70% aluminum alloy and 13% reinforced carbon fiber (CFRP). Audi promotes it as "placing the right material in the right quantity at the right place."

The aluminum panel forming of the R8 utilizes the hydroforming process, which creates the perfect aerodynamic curvature for the vehicle.

The Tesla Model S is constructed with a lightweight aluminum alloy, which makes up 97% of its body. The cost of one roll of aluminum material is $30,000, and the production of the entire vehicle requires 50-60 different aluminum coils. The full aluminum body weighs only 190kg.

The series-connected hydraulic stamping production line (Schuler SMG hydraulic tandem stamping press lines) used by Tesla is the largest in North America and the sixth largest in the world. It has a total tonnage of 11,000 tons and produces one aluminum stamped part every 6 seconds. The production line is capable of producing 5,000 parts per day.

Jaguar has established its first dedicated full-aluminum car body workshop in the Chongming Factory, which is the first of its kind in China. The new model, the long-wheelbase version of the XF, has an aluminum application ratio of up to

It is understood that the new Jaguar factory in Changshu utilizes the world's fastest 5-axis servo stamping production line (3 seconds/piece, high-speed servo press line) and the world's fastest mechanical stamping production line (4 seconds/piece). These production lines allow seamless switching between steel and aluminum materials, and 75% of the molds can be used for both the high-speed servo stamping line and the mechanical stamping line.

In summary, vehicles with all-aluminum bodies are lighter, more fuel-efficient, safer, offer better handling, and have superior corrosion resistance. They represent a major trend in the future development of lightweight automobiles.

As for the aluminum stamping process, which is the primary step in manufacturing all-aluminum body vehicles, it is expected to undergo technological advancements. Whether it is hydraulic forming, servo forming, or aluminum casting extrusion, the solution that achieves a balance between production capacity, quality, and cost will likely become the mainstream in aluminum stamping processes.
