What are the advantages of aluminum body riveting technology for electric vehicles?

Therefore, aluminum body is generally more corrosion-resistant. In addition to the longer body life, it can also save process costs. For example, Chery eQ7 adopts an original short-process aluminum-based process, which directly eliminates the stamping and painting processes of the traditional white body, reducing manufacturing energy consumption by 97% and reducing environmental pollution by 63%.

Excellent electric vehicle aluminum body riveting technology should have high strength, high reliability and accuracy.

The advantage of riveting and gluing technology is that it can greatly enhance the strength of the Chery Jaguar body. The all-aluminum body itself has better energy absorption in high-intensity collisions, and the body connected by riveting technology can withstand longer and more violent collisions.

It is undeniable that it does have technological advantages over welding. For example, the deformation is small and the construction conditions are low. It can be a metal of different composition or a metal of different thickness. Moreover, the strength of riveting is also relatively high, and it is not easy to crack.

The weight of five adult men has been reduced from the car at once. The benefits of lightweighting the all-aluminum body are self-evident, from power performance, fuel economy to handling performance will be greatly improved.

Nowadays, in the construction of new energy vehicles, most of them use all-in-one die-casting technology, so this technology must have its advantages when it is widely adopted. Let's take a look at the advantages and disadvantages of all-in-one die-casting.

Car aluminum alloy wheels haveWhat are the advantages

1. The following are the advantages of automobile aluminum alloy wheels: good heat dissipation: the heat transfer coefficient of aluminum alloy is three times greater than that of steel. Compared with steel hubs, aluminum alloy hubs can transfer these heats into the air faster and increase the safety factor.

2. As the name implies, aluminum alloy wheels are made of aluminum alloy. Compared with traditional steel wheels, it has the advantages of good heat dissipation, light weight, high precision and beauty. The proportion of aluminum alloy wheels is smaller than that of steel wheels, and the average weight is about two kilograms lighter than that of steel wheels of the same size.

3. Alloy hubs have the advantages of light weight, small inertial resistance, high production accuracy, small high-speed rotation deformation, small inertial resistance, etc., which is conducive to improving linear driving performance, reducing tire rolling resistance, and reducing fuel consumption. The thermal conductivity of alloy materials is about three times that of steel, and it has good heat dissipation.

4. The advantages of alloy hubs are light weight, small inertial resistance, high production accuracy, small deformation when rotating at high speed, and small inertial resistance, which is conducive to improving the straight-line driving performance of the car, reducing tire rolling resistance, and thus reducing fuel consumption.

5. Advantages of aluminum alloy hubs The wheels are composed of hubs and tires to support the weight of the whole car. The size and width of the aluminum alloy wheel hub directly affect the size of the tire, and the size of the tire has an important impact on the performance of the vehicle. Aluminum alloy hubs have many advantages over steel hubs.

Will the aluminum alloy wheel hub be scratched and rusted

1. Volkswagen's wheel hub scratched will not rust, which is an aluminum alloy wheel hub. The hub is the part where the axle is installed in the center of the wheel, which is often called "wheel rim" or "steel rim". The hub is easy to get dirty. If it is not cleaned for a long time, it may be corroded and deformed, resulting in safety hazards.

2. Aluminum alloy will not rust. Aluminum alloy wheel hubs have a variety of structural designs such as integral and multi-piece combination in the structure; in terms of appearance, there are a variety of structural designs such as wide spokes, narrow spokes, multi-spokes and few spokes.

3. This is an aluminum alloy wheel hub, which will not rust without treatment.It is necessary to evaluate whether the hub needs to be repaired according to the specific situation: according to the material of the hub: the surface of the hub with electroplating and polishing is very bright, so it is not necessary to repair. Another reason is that the repair is too expensive and not worth repairing.

4. Aluminum alloy will not rust, and scratches cannot be removed. There is no good way to deal with it for the time being. Advantages of aluminum alloy hubs: (1) Compared with steel car hubs, the advantages of aluminum alloy hubs are more obvious: small density, about 1/3 of steel, which means that aluminum alloy hubs of the same volume will be 2/3 lighter than steel hubs.

5. Aluminum alloy, scratches will not rust, but the dynamic balance may be damaged.

Do automobile aluminum plates need to be passivated

The second use is mostly chemical plating, such as: aluminum antique, aluminum blackening, aluminum polishing, aluminum passivation, aluminum coloring, etc. For details, you can refer to the various chemical plating methods of Guangzhou Yishun Chemical on the surface of aluminum; the third is ordinary electroplating, nickel plating, tin plating, chrome plating, etc.; Finally, you can also choose to spray paint and spraying.

After the surface of the aluminum plate is only wiped with passivation, the surface of the aluminum plate will have a layer of paint-like film, which can effectively prevent oxidation and corrosion of the surface of the aluminum plate, thus prolonging the service life. According to the relevant information of the query, the passination solution cannot improve the finish of the surface of the aluminum plate, but the surface will still be rough after wiping.

) After passivation treatment, it has the characteristics of absolutely not increasing the thickness of the workpiece and changing the color, improving the precision and added value of the product, and making the operation more convenient; 2) Due toThe passivation process is carried out in a non-reactive state, and the passivatizing agent can be added repeatedly, so it has a longer life and is more economical.

Hydrogen peroxide can be passivated, but your passivation performance is not very good. It is difficult for die-cast aluminum to achieve 24 hours of salt mist. It is recommended that you use a special aluminum passivation solution. At present, there are two kinds of aluminum passivation solution, one with chromium and the other is chromium-free. If the customer has a clear request, try to use chromium-free solution. The passivation liquid is better.

can make the aluminum shiny. Please refer to the instruction manual of aluminum polishing agent from Guangzhou Yishun Chemical. Finally, passivation treatment is carried out, and the passivation liquid of aluminum is soaked. The purpose is to generate a layer of passivation film with excellent anti-corrosion on the surface of the aluminum, which can maintain the gloss of the surface of the aluminum for a long time. Hope to help you.
