In recent years, the aluminum industry has begun to enter the sign industry and has achieved good results. In modern marking systems, aluminum has a large market share.

Aluminum alloy is a kind of precious metal, which has a matt metallic texture, noble but not arrogant, and can have special texture effects through some surface treatments. Its biggest features: 1. Light weight-because the weight of the aluminum sheet is 2.71kg/mm ​​per square meter, the panel can be thick to 3mm or more, which greatly increases the flatness of the font surface; 2. It is not easy to rust-aluminum sheet Oxidation is slow, and there will be no rust stains on the wall; 3. Easy to color-easy to adhere to the paint film, if processed properly, the surface durability is almost comparable to the car topcoat; 4. Easy to install-because of the low weight, installation is easy Much lighter.

The material selected for the label is mainly determined according to the effect after processing, in which the reference principle of material science is applied. From the perspective of ergonomics, a variety of factors should be considered in the design of a product in a specific environment: the ease of use of the product, the reliability of installation, and the low consumption of maintenance. However, the popular module structure-oriented series products abroad have fully considered these needs. In addition, the precious metal aluminum alloy, which has many advantages, is used as the material, which can increase the grade of the logo.

Compared with traditional materials, it does not rust, has various surface treatment forms, and the content information can be replaced independently. The subsequent use cost is low and the maintenance is extremely convenient. This kind of product began to be introduced to the country in a large amount in the mid-1990s, and it has been widely used in some high-end environments with relatively strong requirements for uniformity, especially in hospitals. It was quickly accepted by some environments and replaced the traditional copperplate etching. , Plexiglass printing and other products. However, due to the need for personalized appearance, some environments require personalized design, but compared with module materials, the cost of personalized production will be higher.
In addition to the selection of the base material, the surface treatment should also be considered. For example, in a public environment such as a hospital, the logo emphasizes its clarity and readability. Therefore, the matte color paint surface treatment replaces the glossy color paint, which solves the problem of copperplate and stainless steel. The reflection problem of materials such as brand and glass. Now more hospitals accept this process for manufacturing, because the extremely low maintenance cost is a measure of the "performance-price ratio" for operators.
Its shortcomings are also obvious. First, the cost is slightly higher, and it needs to be produced by a professional factory. The welding process is similar to stainless steel, but the aluminum plate is soft, and the level of the processor during the welding process will directly affect the flatness and reliability of the surface of the finished word, and the welding spot is large, which is not easy to polish and smooth. This also makes aluminum alloy logos inadequate in modern logo design, because modern logos require not only a unified image, but also characteristics. The difficulty of aluminum alloy welding technology limits it to be profiled and the diversity of product series. Moreover, the surface process effect of aluminum alloy is single. In some places with poor light, aluminum alloy logos are poorly recognizable in places without light sources.
In addition to the sign industry, aluminum also plays a huge role in the aerospace industry. Today's airplanes are mostly made of aluminum. In terms of fighter planes, the demand for aluminum is very large.
