“Prestige creates trust - Quality creates value”

Aluminum is widely used in the light-duty automotive industry due to its high strength-to-weight ratio, corrosion resistance, excellent formability and machinability, which can reduce vehicle weight, reduce fuel consumption, and reduce vehicle weight. Lower energy consumption and reduced emissions.

With the increase of global environmental pollution and energy crisis, reducing car weight and fuel consumption has become an important direction for the green development of the auto industry. Based on statistics, a 10% reduction in vehicle weight will reduce fuel consumption by 6 – 8%. Therefore, the light weight of cars is of great importance, not only to alleviate the energy crisis but also to contribute to effective control of environmental pollution.

Common types of aluminum in the automotive industry include: 1050, 1060, 3003, 3105, 5052, 5083, 5182, 5454, 5754, 6061, 6016, 7075, 2024.

1xxx series aluminum grade: has excellent corrosion resistance and high formability used to produce parts such as heat shields and license plates. Common alloys are 1050 and 1060. In addition, 1xxx aluminum foil is also widely used for EV battery cores.

2xxx series aluminum grade: It has good strength and wear resistance, often used to produce automobile engine and transmission parts.

3xxx series aluminum grade: It has good thermal conductivity and corrosion resistance used to produce automotive heat exchangers such as radiator cores, intercoolers and condensers. Common alloys are 3003,3004,3105.

5xxx series aluminum grades: 5052, 5182,5083 and 5754 have high strength, excellent formability and good corrosion resistance. These alloys are commonly used in the manufacture of automotive body panels, such as hoods, trunk lids, doors, fenders and chassis. In addition, alloys 5052 and 5083 are used to produce fuel tanks and hydraulic oil tanks. It will not create sparks when rubbed with other hard objects, greatly improving safety during use. Therefore, fuel tanks made of aluminum material are preferred for large buses and heavy trucks with high fuel consumption and high requirements for fuel quality.

6xxx series aluminum grade: It has a high strength-to-weight ratio, good formability and excellent corrosion resistance. And these alloys also have good weldability, which can be used for automobile door and window frames, wheels, suspension systems and other parts. Especially 6016,6061 and 6063.

7xxx series aluminum grade: It has extremely high strength and stiffness and is often used in the production of high-performance vehicles such as racing and off-road vehicles, for their frames, chassis and suspension systems.
