The Use of 6016 and 6101 Aluminum in Car Making

 

6016 aluminum sheet

6016 aluminum alloy is an Al-Mg-Si-Cu alloy developed by Alcoa. It has good fracture toughness, corrosion resistance and fatigue-relieving properties, especially excellent in forming performance, so it is widely used in the automotive field.

The outer plate of automobile covering parts is an important application direction of en aw 6016. 6016 aluminum alloy sheets are often used in parts such as automobile hoods, doors, truck lids, and roofs. Taking the outer plate of the automobile hood as an example, it not only affects the appearance and aerodynamic performance of the vehicle, but also needs to take into account lightweight, safety and manufacturing process feasibility.

6016 aluminum alloy has significant advantages in this regard. Its elongation can reach 22-25%, which is much higher than the 15-20% of ordinary steel. This allows it to stamp out complex streamlined shapes such as engine hoods. Moreover, it has a small rebound after stamping, with a rebound angle of about 3-5°, which can effectively reduce dimensional deviation and ensure assembly accuracy.

At the same time, the surface of 6016 aluminum alloy is smooth and has no orange peel after spraying. It has good corrosion resistance due to the natural oxide film and is not easy to rust after long-term use.

In terms of manufacturing process, 6016 aluminum alloy sheets need to go through solid solution treatment, pre-aging treatment (T4P) and baking varnish treatment. After such process treatment, 6016 aluminum alloy sheets can have good forming properties before stamping, and can quickly increase strength during the baking varnish process after stamping, and have high dent resistance.

European automakers generally use 6016 aluminum alloy plates for body panels, and their good forming properties are fully utilized. In recent years, with the increasing demand for lightweight in the domestic automobile industry, domestic companies are also actively researching and applying 6016 aluminum alloys.

6101 aluminum sheet

6101 aluminum alloy belongs to the low-alloyed Al-Mg-Si conductive aluminum alloy, which has high specific strength, good conductivity, corrosion resistance and formability, and has specific application scenarios in the automotive field.

In the conductive system of the car, 6101 aluminum alloy is very useful. For example, the power battery busbar, battery connection plate and other components of new energy vehicles are often made of high-conductivity aluminum alloys such as 6101.

Take the power battery busbar as an example. It is a key component that connects the battery module and the battery management system, and has extremely high conductivity requirements. The high conductivity of 6101 aluminum alloy can reduce resistance, improve energy conversion efficiency, and make the battery charge and discharge performance better, thereby improving the overall performance of new energy vehicles.

In terms of manufacturing process, the processing flow of 6101 aluminum alloy is generally casting - rolling - solution treatment - cold drawing - aging heat treatment. Through such a process, 6101 aluminum alloy can have higher strength and meet the comprehensive requirements of automotive parts in terms of strength and conductivity.

The Use of 6016 Aluminum in Car Making

 Aluminum alloy has the characteristics of light weight, wear resistance, corrosion resistance, high specific strength, good impact resistance, easy surface coloring, etc., and more than 80% of aluminum can be recycled, making aluminum alloy an ideal lightweight material for automobiles.

6xxx aluminum alloys can be heat treated and strengthened, which just matches the existing automobile body production system. It can go through solid solution and pre-aging in the aluminum sheet factory to make them have good formability, and then go to the automobile factory for stamping and forming to manufacture body components.

Then, the aging treatment can be realized directly by means of the baking paint coating and heating production line of the original steel automobile body components, and the obvious strength performance can be improved, so that the aluminum alloy body components have high concave resistance. Therefore, 6000 series aluminum alloys are considered to be the most promising aluminum alloy for car making.

6016 aluminum including 6016 t4 and 6016 t6 aluminum is widely used in ABS, but the heat treatment process is complicated, and pre-aging treatment T4P must be carried out between solution treatment and paint treatment to obtain good performance. Because it has good formability before stamping, and can rapidly increase the strength during the paint baking process after stamping, so it has high dent resistance.

The production process of 6016 aluminum alloy sheet in the aluminum plate factory is mainly as follows: proportioning, smelting, refining, adding grain refiner, casting, sawing, milling, homogenizing heat treatment, hot rolling, heat treatment, cold rolling, heat treatment (double grade aging) -stamping and bake hardening. 6016 t4 aluminum sheet often affects the final bake-hardening effect due to natural aging during transportation to automobile factories.

Compared with the steel plate front anti-collision beam assembly, the use of 6063 and 6016 aluminum alloys to manufacture the front anti-collision beam assembly not only greatly reduces the weight, but also improves the anti-collision effect. 6063 and 6016 alloys are two commonly used wrought aluminum alloys. The manufacturing cost of aluminum alloy crash beams is about 18.5% higher than that of steel beams.

The Automotive Aluminum Sheets: 6016 and 6061

 In recent years, Audi and Jaguar Land Rover have used all-aluminum body structures. Aluminum alloy has become an ideal lightweight material. With different alloy compositions and processing, it can be used for car body, frame, clutch housing, brake parts and cover housing, etc.

In addition to gasoline vehicles, lightweight has also become an important issue for new energy vehicles. Aluminum has also become the most cost-effective choice for electric vehicles. The use of automotive aluminum sheets will effectively reduce the body weight of new energy vehicles, thus freeing up more space for power battery.

The use of car aluminum is mainly concentrated in three aspects: automobile wheels, automobile engine gearbox housings,automobile frames, interior trim, bottom plate,etc. The heat treating aluminum 6061 is a common choice for car wheels.

Aluminum alloys for the car body mainly include 2000 series, 5000 series and 6000 series alloy plates. The most stressed part of the car body is made of 2000 series or 7000 series materials, which can be strengthened by heat treatment.

The cover panel is the secondary stress part of the car body, using 5000 series or 6000 series materials. The car door and bottom plate chooses 5xxx or 6xxxx automotive aluminum. The interior part uses 1000 series or 5000 series materials, without heat treatment strengthening. The seat part chooses 2000 series or 6000 series materials are used, which can be strengthened by heat treatment.

6xxx aluminum alloy is a kind of the heat treatment strengthened aluminum alloys, which have higher strength, better plasticity and excellent corrosion resistance. Compared with steel plates, the yield strength and tensile strength of 6000 t4 plates are similar.

At present, 6009, 6010 and 6016 aluminum alloys are used in the outer and inner panels of automobile bodies because of their good plasticity and high strength. In addition, in order to enhance the cushioning capacity and fatigue strength of automobiles, VAW of Germany, KOK of Japan, and Haomei Aluminum of China have all developed high-performance automotive aluminum plates based on this alloy.
