Aluminum alloy analyzer used in automotive industry alloy materials

[China Aluminum Network] For bus manufacturers, apart from choosing fuel-saving parts, how to reduce the weight of vehicles and reduce fuel consumption is also a problem they must face. Compared to traditional body materials, the application of aluminum alloy analyzers to automotive alloy materials can make the body more lightweight.

The benefits of aluminum alloy materials When it comes to aluminum alloy bus, it is imperative to mention that Yutong and Alcoa jointly launched the first domestic aluminum bus ZK6126HGE in the foreground with the Olympic Dongfeng stunning debut. According to reports, the connection of the ZK6126HGE body piece adopts a combination of welding and riveting, which greatly improves the flatness and aesthetics of the car body. Due to adopting Alcoa's all-aluminum frame design and hard alloy technology, the ZK6126HGE vehicle's weight reduction reaches more than 25%, far exceeding the expectation of a 15% reduction in weight. The weight reduction of more than 1400 kg was realized on this 12-meter urban bus, which means that the weight of the vehicle in the no-load state is reduced by approximately 11.6%. The body weight reduction effect is very obvious. Compared with the traditional steel passenger car body, the body weight can be reduced by 46%.

Not only that, passenger cars using aluminum alloys have greater advantages in terms of safety performance. High-strength machining processes can achieve very light but very good elasticity, and therefore, they are also safer.

With the levying of fuel tax and e-mails, aluminum-alloy passenger cars will save 38,250 liters of fuel over the entire operating cycle due to their lighter weight. The operating cycle of passenger cars is calculated on the basis of 8 years. If the price of diesel No. 0 is 6 yuan per litre, the sample car of all-aluminum car bodies can save about 230,000 yuan in fuel oil during the entire operating cycle.

Forged aluminum alloy wheels are quietly popular Even if all aluminum bodies have this huge advantage, industrialization under the current conditions clearly has a long way to go. Therefore, the use of aluminum alloy materials in the local vehicle has become a better choice, forging aluminum alloy wheels has been widely recognized in the industry, in Beijing, Shanghai, Guangzhou and other places have indicators of fleet and long-distance bus use.

Technical and Cost Obstacles Despite the huge advantages of aluminum passenger cars in light weight, some analysts believe that: “All aluminum body production costs will increase by 40% to 50% compared to ordinary passenger cars, even if all aluminum passenger cars are used and recycled. The utilization aspect is better than that of the traditional passenger car, but the sales price of the all-aluminum bodywork bus is still higher than the fuel cost saved during the entire operation period.

Speedmaster Road forged aluminum alloy wheels in 23-24 kg, the weight of the vehicle reduced more than 160 kg, due to the heat transfer of the alloy wheel is better than the steel tire, the service life can be greatly improved, single tire Higher per millimeter can be increased by 30%. The deformation of aluminum alloy wheels is very small compared with steel, which means that the tires always maintain a good roundness in the starting state, reducing oval resistance due to hub deformation, effectively reducing the loss of engine power and reducing fuel consumption. purpose.
