Aluminium Used in Cars

 Amidst the rapid development of the automotive industry, material innovation remains a key driver of vehicle performance upgrades. Aluminum alloy, with its numerous advantages, such as lightweight, high strength, and corrosion resistance, has long played an irreplaceable role in many key automotive components.

Body Frame

The vehicle body frame is a core structure for ensuring driving safety and significantly impacts vehicle weight. Traditional steel bodies, while strong, are also heavy, increasing fuel and energy consumption. Aluminum alloy body frames perfectly address this dilemma.

Currently, many mid-to-high-end and new energy vehicle models utilize aluminum alloy body frames, such as doors, hoods, trunk lids, and the main body structure. For example, the common 6-series abs aluminum plate has a tensile strength exceeding 300 MPa, enabling a 30%-50% weight reduction compared to steel bodies while maintaining strength. Lightweight bodies not only reduce fuel consumption in combustion-powered vehicles (data shows that every 10% reduction in vehicle weight reduces fuel consumption by 6%-8%), but also extend the range of new energy vehicles. This is why aluminum alloy bodies are increasingly favored in new energy vehicles.

Furthermore, aluminum alloy exhibits excellent corrosion resistance, resisting rust even after prolonged exposure to the elements. This effectively extends the vehicle's service life and reduces maintenance costs. Furthermore, in a collision, the aluminum alloy body frame absorbs impact energy through optimal deformation, better protecting occupants and achieving the "double guarantee" of lightweight and safety.

Chassis System

The automotive chassis is a critical component that supports the vehicle body, transmits power, and ensures driving stability. It demands extremely high material strength, toughness, and wear resistance, and aluminum alloys are widely used in chassis systems.

Firstly, components such as chassis control arms and steering knuckles must withstand the various impact forces and torques experienced during vehicle operation. Aluminum alloys, such as the 7 Series aluminum alloy, offer excellent strength and fatigue resistance, ensuring stable performance over long periods of use and reducing the risk of component deformation or damage. At the same time, lightweight aluminum alloy chassis components can reduce the vehicle's unsprung mass, improving handling and comfort, and providing a smoother driving experience.

In addition, some models also utilize aluminum alloy for their chassis subframes. As a crucial structure connecting the chassis components to the body, the subframe requires sufficient rigidity and torsional resistance. Aluminum alloy not only meets these requirements but also further reduces chassis weight, contributing to the overall vehicle lightweighting.

Powertrain

The automotive powertrain is the "heart" of the vehicle, and its performance directly impacts its power output and fuel efficiency. Therefore, the use of aluminum alloy in the powertrain is crucial.

Among engine components, aluminum alloy is the most widely used. For example, core components such as the engine block and cylinder head are mostly made of aluminum alloy. This is because aluminum alloy has excellent thermal conductivity, allowing it to quickly dissipate heat generated during engine operation, preventing overheating and ensuring stable engine operation.

Furthermore, lightweight aluminum alloy engine components can reduce overall engine weight, minimize power loss, and improve engine power efficiency, resulting in stronger vehicle performance while also reducing fuel consumption. In addition to the engine, aluminum alloy is also commonly used in transmission cases. Transmissions generate a certain amount of heat and vibration during operation. Aluminum alloy not only effectively dissipates heat but also offers certain shock-absorbing properties, reducing noise and vibration during transmission operation and improving driving comfort. Furthermore, a lightweight transmission case further reduces the weight of the powertrain, contributing to the overall vehicle lightweighting.

Interior and Accessories

Beyond core components such as the body, chassis, and powertrain, aluminum alloy is widely used in automotive interiors and accessories, adding a touch of sophistication and practicality to the interior.

In automotive interiors, aluminum alloy is often used in decorative parts such as center console trim, door trim, and shift paddles. These aluminum alloy decorative parts not only have a metallic texture and a refined and beautiful appearance, enhancing the interior's sense of class, but also offer excellent wear and scratch resistance, maintaining their appearance over time and resisting fading or damage.

Aluminum alloy is also commonly used in automotive accessories. For example, most passenger cars on the market now use aluminum alloy wheels. Compared to traditional steel wheels, aluminum alloy wheels are lighter, reducing a vehicle's unsprung mass and improving handling and fuel efficiency. They also offer improved heat dissipation, effectively dissipating heat generated by the tires and brake system, reducing tire wear and the risk of brake overheating. Furthermore, aluminum alloy wheels come in a variety of shapes and designs, offering greater design flexibility to meet the personalized needs of different consumers.

Automotive aluminium is also commonly used in components such as sunroof frames and seat rails. These components require excellent wear resistance and smoothness, and aluminum alloy not only meets these requirements but also reduces component weight, improving user convenience and comfort.

There are many alloy grades of 6 series aluminum profiles, the most commonly used ones are 6463, 6262, 6201, 6082, 6063, 6061, 6010, 6009, 6005, etc. Aluminum-magnesium-silicon alloy is the most commonly used aluminum alloy in wires and cables, which are 6101 aluminum and 6201 alloys, and the states are T1 and T4. In 2020, the global consumption of this aluminum alloy exceeded 5000kt.

6101 aluminum alloy wire has medium strength and high conductivity, and can be used for long-distance transmission lines. Compared with traditional steel core aluminum alloy stranded wire (ACSR), the all-aluminum alloy stranded wire (AAAC) twisted by a single Al-Mg-Si alloy wire can well avoid electrical corrosion, and can reduce the maintenance cost of transmission lines while improving transmission efficiency. At the same time, Al-Mg-Si series alloys are heat-treatable strengthening alloys, and their strength and conductivity can be adjusted by solid solution + aging heat treatment.

5754 aluminum sheet is mostly used by automobile manufacturers abroad, such as door panels, engine covers, or trunk covers. Usually 5754 aluminum sheet is processed into H111 state or H0 state through annealing, because it can only be bent in this state, and of course the price is higher than 5052 aluminum alloy sheet.

5754 aluminum alloy is a typical alloy in Al-Mg alloy series, with medium strength, good corrosion resistance and weldability, easy processing and forming, etc. 5754 aluminum alloy plates in different heat treatment states are widely used in welding structural parts, large roof panels, automobile manufacturing, rail transportation and shipbuilding industries, among which H32 state aluminum plate is one of the most widely used heat treatment states.

6016 Automotive Aluminum Sheet

 The automotive aluminum sheets can be classified into 5000 series, 6000 series and 7000 series in terms of alloy composition. 5754, 5182, 5023 are used for inner covering parts and structural parts; 6016 aluminum, 6014, 6022, 6111 are used for outer covering parts.

6000 aluminum alloys are currently the most widely used aluminum alloys for automobile sheet metal parts in the automobile industry. They have excellent formability, high strength performance, corrosion resistance, hemming performance, high surface performance, etc. At the same time, after painting and baking, the strength performance has been improved to a certain extent.

6009, 6010 and 6016 aluminum alloys are currently used in the outer and inner panels of automobile bodies due to their good plasticity and the artificial aging that can be achieved in the process of painting and baking after forming to obtain higher strength.

6016 aluminum sheet is used in the outer panel of the car door, which can meet the dent resistance design requirements by increasing the thickness of the sheet and optimizing the structure. Under the premise of meeting the rigidity, strength design requirements and relevant collision regulations, AA6016 aluminum alloy plates can be widely used to replace traditional steel plates in the outer panels of automobile doors, so that the weight can be reduced by more than 40%, and the purpose of lightweight can be achieved.

The 6061 alloy reaches medium strength after special treatment (T6), and its strength is higher than that of the 5 series alloys. Moderate strength is very suitable for the automotive industry. The aluminum alloy sheet used for different parts of the automobile body is also different. Among them, the 6061 aluminum sheet is used for the car fender, outer hood panel and car door.

The 6016 aluminum sheet can meet the vehicle manufacturing requirements after the solid solution-T4P-baking paint treatment, but the process parameters have a great influence on the final performance.

Insufficient solution treatment reduces the precipitation power of T4P and artificial aging during the baking process. Long holding time may lead to grain coarsening. Low pre-aging humidity will reduce the performance stability of the plate during placement and the hardening effect during the baking process.

If the temperature is too high, it will affect the formability of the stamping process. It can be seen that the solid solution and T4P process parameters should be optimized in order to obtain ideal comprehensive properties.

5083 6061 Aluminum Sheet for Bus Body

 For the buses, the trend of new energy has been unstoppable. In major and medium cities, pure electric and other new energy buses have been put into operation. However, at present, there has always been a serious problem for new energy buses, especially pure electric buses.

Due to the addition of a large number of battery packs to the vehicles, to a certain extent, compared with fuel buses, at least 1- 2 tons weight is added. Originally, there is a problem with the battery life of pure electric buses, and such an increase in weight greatly reduces the cruising range of the vehicle.

In terms of realizing the lightweight of the body and the weight reduction of the whole vehicle, the all-aluminum body structure has become the most effective way. With its excellent characteristics, it has been set as the standard configuration of the body frame and skin of new energy buses, especially pure electric buses, by many bus OEMs and bus companies.

The frame of the whole vehicle is welded by 6 series aluminum alloy, and the skin is completed by 5 series aluminum plate. The aluminum bus body brings long cruising range, and its weight reduction ratio is more than 30% compared with the general steel body. The car adopts a low entrance structure, and the interior space is spacious, with a maximum passenger capacity of about 80 people.

The main aluminum used in the bus is 6061 t6 aluminum plate. The main connecting parts are fully riveted. The weight of our 12-meter bus has been reduced by 500kg to one ton. The 12-meter city bus that has been supplied in batches weighs about 920 kilograms.

Vans and semi-trailers both adopt lightweight frame. The material is generally high-strength aluminum alloy (or high-strength steel plate), and equipped with air suspension , aluminum alloy rims, 425/65R22.5 tires,etc.

For example, the tank body of oil tanker produced in China is made of marine grade aluminium 5083 6mm sheet. The front and rear heads are made of 5083 7mm thick aluminum alloy.

On the premise of ensuring the quality, the weight of the body is greatly reduced, and the weight of the whole vehicle is only 7600kg (the weight of the ordinary steel structure 3-axle liquid tanker is about 11 000kg).
