Comprehensive Automotive Aluminum Rod

The core advantage of aluminum alloys in the automotive industry lies in their superior lightweight properties, effectively reducing vehicle weight and thus significantly improving fuel economy or the driving range of electric vehicles, while also reducing emissions. This makes them the preferred material for automotive lightweighting. Simultaneously, they possess excellent energy absorption properties, contributing to improved collision safety, as well as good corrosion resistance and high recyclability, meeting the requirements of green manufacturing and the circular economy.

Driven by the wave of automotive electrification and intelligentization, their applications are rapidly expanding from traditional engines and wheels to new energy-specific fields such as battery trays and body structural components. New processes such as integrated die casting can significantly reduce the number of parts and improve production efficiency, while new material technologies such as rare earth modification continue to improve performance and optimize costs.

Common Automotive Aluminum Alloy Series

1100 Automotive Aluminum

1xxx series aluminum is the purest aluminum currently available. 1100 aluminum is 99% pure and extremelyductile. It also has excellent corrosion resistance and is primarily used for thermal insulation.

2024 Automotive Aluminum

2xxx series aluminum contains copper as an alloying element. 2024 finds common use in making pistons, brake parts, rotors, cylinders, wheels, and gears because of its high strength and excellent fatigue resistance.

3003 Automotive Aluminum

3003 has high strength, good formability, machinability, and elongation. It is commonly used in automotiveducts, panels, and power castings for hybrid and electric vehicles.

5005,5052,5083 Automotive Aluminum

The 5xxx series is one of the most popular series of aluminum alloys for car bodies. Its main alloying element ismagnesium, which is known for increasing strength.

• 5005 finds main use in the manufacture of automotive interior and exterior trim parts, body panels, radiator components, etc.

• 5052 is present in automotive parts such as fuel tanks, truck trailers, suspension panels, display panels, brackets, disc brakes and drum brakes.
• 5083 is ideal for making complex automotive parts such as engine mounts and body panels.

6016,6022,6061,6082 Automotive Aluminum

The 6xxx aluminum series has the best extrusion and casting capabilities and offers the best surface finishes.

• 6016 and 6022 find use in automotive body coverings, doors, trunks, roofs, fenders and outer panels where dent resistance is critical.
• 6061 ahas excellent surface treatment characteristics, corrosion resistance and high strength. It is used to makebeams, brakes, wheel drive shafts, truck and bus bodies.
• 6082 has the best impact resistance. Therefore, it can be used in load-bearing frames.
