Auto Body Metal Aluminum 5052 5083

Aluminum, as a representative material for automobile lightweighting, is crucial to the development of today's automobile industry. The formability and production performance of aluminum plates are very close to those of steel plates. Therefore, using aluminum alloys instead of steel materials is one of the main weight reduction methods adopted by automobile manufacturers in various countries.

After searching the existing technology, it was found that the aluminum alloy inner panels used in automobiles are mainly 5xxx series alloys, such as 5052, 5182 alloys, etc. In terms of deep drawing performance and tensile strength, 5052 aluminum alloy is far less good than 5182 alloy. 5052 h32 alloy aluminum sheet is often used for the bus skin.

In the Al-Mg alloy, Mg is dissolved in the aluminum matrix, forming a solid solution strengthening effect, which makes the alloy have the advantages of ordinary carbon steel plates in terms of strength, formability and corrosion resistance. It can be used for complex shapes such as automobile inner panels.

For example, 5083 alloy aluminum plate is used for the floor and side walls of tank trucks and dump trucks; 5182 alloy aluminum plate is used for containers and tanks carrying powders and dangerous goods (gas, fuel). The four walls of the refrigerated truck are made of three layers of composite materials, with the upper and lower layers made of aluminum alloy plates and the middle layer made of thermal insulation material. The side panels and inner panels of the semi-trailer's body are made of 4-5mm thick 5052 alloy.

5083 alloy is a typical 5XXX series alloy and a typical automotive sheet alloy. Aluminium 5083 h111 is a popular choice. It has excellent weldability, corrosion resistance, processing and formability and low temperature properties. Among Al-Mg series alloys, it has medium strength properties. The strength of the welded joint can be equal to that of the base material in the annealed state, and it has reliable corrosion resistance.

The mechanical properties of the alloy increase evenly as the temperature decreases, as does the fracture toughness. It is a good automotive covering. Alloy, especially suitable for internal and external welding sheet metal structures of commercial vehicles, various special vehicles, semi-trailers, etc.

Dump trucks are the main trucks used to transport granular and powdery materials. The body of the dump truck is made of aluminum plate products mainly 5083 aluminum plate and 5A05 aluminum plate. The welding part is made of 5183 aluminum alloy. The body of the car is welded with an aluminum plate of about 5mm.

The interior is lined with steel plates. The aluminum alloy dump truck is 50% lighter than the original all-steel truck, but its performance, load-bearing and other properties can meet the requirements. Dump trucks are also the main direction of current all-aluminum trucks.
