The "four transformations" of new energy vehicles: lightweighting, intelligence, networking, and electrification. 

In the era of new energy, various industries such as automotive batteries, lightweighting of vehicle bodies, and automotive components have brought an extremely broad market opportunity to China's aluminum industry. What is the use of aluminum sheets used in new energy vehicles? What are the advantages? What alloys are there? 

With the development of automobiles towards lightweighting and the significant increase in the use of new energy vehicles, the usage of aluminum in new energy vehicles has grown at a rate of around 30% annually! The "range requirement" has greatly increased the usage of aluminum in new energy vehicles. By 2025, the annual growth rate of domestic aluminum rolled plates and extruded materials will reach around 30%! All major automobile manufacturers are targeting materials such as aluminum used in new energy vehicles. 

According to relevant data, replacing traditional steel structures with aluminum in new energy vehicles can reduce the vehicle weight by 30% to 40%, the production of engines by 30%, and the production of wheels by 30% to 50%. The use of aluminum in new energy vehicles is one of the important ways for automotive lightweighting, environmental protection, energy saving, acceleration, and transportation. In addition, the main advantages of using aluminum in new energy vehicles are its light weight and good heat dissipation. Therefore, it is very necessary to develop aluminum automotive components for new energy vehicles. 

The core technologies of bicycles mainly include manufacturing techniques and performance technologies. Even just looking at a bicycle frame tube, there is a lot of knowledge involved. The bicycles we ride nowadays are mostly professional ones, with prices ranging from several thousand to tens of thousands of dollars. Apart from brand value, the difference in price to some extent reflects the different materials and manufacturing techniques used in the production of the bicycles. So, let's now take a look at what materials are best for bicycle frame tubes? 

First, I will briefly explain the importance of the size of the bicycle frame tubes. The size must be suitable for your body. If it is too large or too small, it will affect your riding posture, making it more difficult to ride a bicycle compared to others, and prolonged use may lead to movement disorders. However, this is not absolute. For example, if you often go downhill, you should reduce the frame size. If it is only used for traveling on flat roads, a slightly larger size is fine. But the experience in choosing the frame size should be "prefer smaller over larger". Then, let's learn about the method for choosing the size of bicycle frame tubes.
