Conclusion: Compared with carbon fiber, CNC magnesium aluminum material has adjustable color, controllable technology and lower cost.
The notebook manufacturing and design process is suitable for CMF industrial design system, where C stands for color, M stands for material and F stands for completing the process. The appearance and feel of the product are within its scope.
First, colors can be customized to meet different people's aesthetics.
Although carbon fiber materials have the characteristics of light weight, high strength, high modulus, high temperature resistance, corrosion resistance, erosion resistance and sputtering resistance, most of them are still dominated by black in front of consumers, which determines that it is more suitable for business people.
Carbon fiber material is mainly black.
At present, the mainstream metal material is alloy, and the main synthetic metals are aluminum, magnesium, stainless steel, titanium and so on. For example, magnesium-aluminum alloy and aluminum-magnesium alloy are distinguished because of the different proportions of the two materials. Magnesium-aluminum alloy has better strength and lighter weight than aluminum-magnesium alloy. Of course, there are also titanium alloy and lithium magnesium alloy products.

In the whole production chain, metal materials need NC forming, stamping and sandblasting, and the coloring part is usually in the last coating part of anodic oxidation. We often see champagne gold, coffee gold and other colors are colored by the last anodic oxidation. In theory, you can mix all the colors you can think of.
Secondly, NC machining of controllable alloy materials has high hardness.
Metal materials are usually cut by numerical control technology when they come out of the assembly line, while alloy materials just conform to the characteristics of numerical control cutting. A whole metal plate can be cut at high speed with a tool with extremely high hardness, which can reduce the generation of notebook parts and make it more integrated.
In addition, the surface sandblasting process can also improve the texture of the whole alloy material. Compared with carbon fiber, the metal texture is more delicate and natural, and the final coating technology of anodic oxidation presents a high-quality texture.
Usually, the anodized metal after treatment is several times or even dozens of times that before.
After nearly 20 processes, such as degreasing, alkali washing, neutralization, chemical polishing, oxidation, dyeing and hole sealing, the anodic oxidation process is very close to the notebook mold we use. This process has many characteristics such as thickness, uniformity, hardness, corrosion resistance and insulation.
Anodizing is a very magical chemical reaction, because the texture of aluminum itself is very soft, and to what extent, for example, the hardness of ordinary glass is 5.5 Mohs hardness. Mohs hardness is a standard of mineral hardness, also known as Mohs hardness. The hardness of aluminum itself is only 2-2.5 Mohs hardness, and the hardness of aluminum after anodic oxidation can reach 9 Mohs hardness. If other metals such as magnesium and aluminum are added, the hardness will be higher.
Although carbon fiber material has strong rigidity and hardness second only to diamond, its impact resistance is poor. When the material is torn, the fiber splash is easy to cause secondary damage, and it is oxidized under the action of strong acid, so its stability is not as good as that of alloy material, and alloy material is obviously superior to carbon fiber material in heat conduction.
Third, the cost of alloy materials and carbon fiber materials is not an order of magnitude.
The production of carbon fiber is a very complicated system engineering. At present, the domestic carbon fiber production is limited, and only T300 and T800 materials can be produced independently. Their customers are mainly for national key enterprises such as military industry and aerospace, and private enterprises can hardly get domestic carbon fiber products. Therefore, almost all our common civil carbon fiber materials are imported, and the imported products, including customs declaration and patent tax, are doomed to be very expensive at the bottom cost.

Common materials such as aluminum, magnesium, titanium, copper and stainless steel can be found everywhere in the vast land of China. From mining to processing and refining, China, as a factory in the world, is almost familiar with it, so the production and manufacturing costs are naturally lower. In other words, on the premise of the same configuration, do you prefer to buy a magnesium-aluminum alloy notebook with a beautiful appearance of 4,000 yuan or a lightweight carbon fiber notebook with a price of more than 10,000 yuan? I think most major purchases will choose the former.
Editor's comment: Imported material patents restrict various taxes and fees, which leads to the fact that carbon fiber materials are not cheap, so notebooks using carbon fiber materials in a large area are bound to cost more than 10,000 yuan. Products made of alloy materials have become the mainstream of the market because of their good plasticity, corrosion resistance, mature technology and low cost. It has been favored by most manufacturers and consumers. The author believes that there is no difference between good and bad products, only those that suit you. Carbon fiber notebook is really excellent, but magnesium-aluminum alloy is not bad, just like steak, western food and home-cooked meals, you should buy it according to your actual situation.
