aluminium show |The Mi SU7 Uses Aluminum Wire Instead of Copper Wire? Xiaomi Responds: Aluminum Wire is the Industry Trend

Recently, Xiaomi SU7 suppliers exposed that Xiaomi SU7 uses aluminium wires instead of copper wires, which sparked widespread discussion. Xiaomi quickly responded, stressing that the use of aluminium wires is an industry trend that aims to bring users a better experience. Xiaomi said that traditionally, copper wires are widely used in electronic devices due to their good conductivity and stability. However, with the advancement of technology and the development of the industry, aluminium wires are gradually showing their unique advantages. Aluminium wire is lighter and softer than copper wire. With the same volume aluminium wire is 30% lighter than copper wire, which means that it offers greater flexibility in terms of the internal layout and design of equipment. Reduced weight also means reduced energy consumption.

According to the Aluminium Show, the cost of aluminium wire is relatively low, which helps to reduce the overall cost of the product, and bring users a more affordable price, which is also in line with Xiaomi’s usual style. In the case of the same product quality, the use of more affordable materials means a better benefit to consumers, and there is nothing wrong with it. Xiaomi said that this is an adjustment based on market trends and user demand. As a more lightweight connection wire, aluminium wire can effectively reduce the weight, and thus now becomes the industry's new favourite. This is an overwhelming trend amid the development of the entire automotive industry. Xiaomi also stressed that the use of aluminium wires does not damage the performance and stability of the device, but rather, it helps to improve user experience. In addition, Xiaomi also pointed out that aluminium wires also have significant advantages in terms of environmental protection. Aluminium is a recyclable metal. Compared with other metals such as copper, its mining and processing has less impact on the environment. The use of aluminium wire can help promote the green development of the whole industry.
