Aluminum Alloys and Its Special Vehicles

In fields such as logistics, construction, and emergency rescue, specialized vehicles, with their customized functional designs, ensure efficient operation. With the increasing demand for lightweight and high-strength vehicles, aluminum alloy, with its advantages of low density, corrosion resistance, and recyclability, is gradually replacing traditional steel and becoming a core material for specialized vehicle manufacturing.

Specialized Vehicle Types

Cold Chain Logistics Vehicles: Primarily used for transporting perishable goods such as fresh produce and pharmaceuticals, these vehicles require thermal insulation and lightweight construction. They must reduce vehicle weight to increase cargo capacity while ensuring a stable box structure to prevent material embrittlement in low-temperature environments.

Tank Trucks: These include tankers, chemical liquid transporters, and powder and granular material transporters. Key requirements include corrosion resistance and strong sealing, requiring resistance to oil, acid, and alkaline solutions, while also ensuring strength to withstand the weight of the media.

Specialized Construction Vehicles: These include concrete mixer trucks, aerial work platforms, and excavator transporters. These vehicles operate in high-intensity environments for extended periods, placing extremely high demands on material fatigue and impact resistance. They must also be able to withstand the complex dust and muddy conditions of construction sites. Emergency rescue vehicles, including fire trucks, ambulances, and disaster relief vehicles, must respond quickly in emergency situations. Materials must meet multiple requirements: lightweight (to increase vehicle speed), high strength (to ensure rescue safety), and easy processing (to accommodate specialized functional layouts).

Municipal service vehicles, such as garbage trucks, sprinklers, and road sweepers, operate frequently on a daily basis. Materials must be wear-resistant and easy to clean. Lightweight designs can also reduce fuel consumption and lower long-term operating costs.

5-series aluminum alloys

5-series aluminum alloys, with magnesium as the primary alloying element, feature low density (approximately 2.68g/cm³), a specific strength close to that of steel, and excellent corrosion resistance. They are widely used in specialized vehicles. Different grades, finely tuned by composition, are suited for specific applications:

5052, 5A06: 5052 offers excellent formability and can be processed into curved cold chain vehicle panels, reducing vehicle weight by 15%-20% and increasing range. 5A06 offers higher strength, making it suitable for garbage truck bodies to withstand the impact of loading.

5083: Among 5-series aluminum alloys, 5083 aluminum sheet has the highest strength (tensile strength of approximately 370MPa) and excellent resistance to marine atmospheric corrosion and fatigue. It is suitable for tank trucks (such as those transporting sea salt and desalination agents) that frequently travel to coastal areas, as well as the frames of engineering support vehicles used in offshore platforms. It effectively resists corrosion from seawater salinity while also withstanding certain load shocks. 5754: Its shapeability is superior to 5083, its corrosion resistance is similar to 5052, and its weldability is excellent. It is commonly used in the joints of cold chain logistics vehicles and the side panels of municipal sprinkler trucks. Its excellent shapeability allows for complex bending processes and is less prone to cracking after welding, ensuring the tightness and stability of component connections, preventing problems such as cold chain boxes and sprinkler trucks from leaking.

5059: This high-strength 5-series aluminum alloy boasts a tensile strength of up to 420 MPa while maintaining excellent corrosion resistance. It is suitable for guardrails in construction vehicles (such as the side guardrails of excavator transport vehicles) and door frames in emergency rescue vehicles. These components must withstand the impact of collisions and resist rust in outdoor environments. 5059 aluminum meets both strength and corrosion requirements.
