The aluminum alloy has the characteristics of light weight, but the mechanical properties are obviously improved. The application of aluminum alloy materials includes the following three aspects:
First, it is used as a force member;
Second, it is used as materials such as doors, windows, pipes, covers, shells, etc;
Third, it is used as decoration and insulation material.
Various decorations can be made by using the characteristics of Anodizing of aluminum alloy. Aluminum alloy plate and profile surface can be processed for secondary processing such as anticorrosion, rolling, painting and printing, and various decorative plates and profiles can be made as decorative materials. It is one of his characteristics that the cost is low and the same parts can be produced in large quantities by using a processing technology. Several layers of carbon fiber may be used when making a larger part, which will become one layer by one like a cake when it exceeds the force capacity. And aluminum alloy will be deformed and damaged after it is subjected to certain force. And it is easy to process and have high heat dissipation. Especially, the engine part of the vehicle is particularly suitable for the use of aluminum alloy materials. It is almost entirely aluminum alloy. In addition, the processing technology of aluminum alloy is various. It is more general.
Advantages of aluminum alloy:
1. Low density
The density of aluminum and aluminum alloy is close to 2.7g/, about 1/3 of iron or copper.
2. High strength
Aluminum and aluminum alloy have high strength. After a certain degree of cold processing, the strength of the matrix can be strengthened, and some aluminum alloy grades can also be strengthened by heat treatment.
3. Good conductivity
The conductivity of aluminum is second to silver, copper and gold.
4. Good corrosion resistance
The surface of aluminum is easy to produce a dense and firm Al2O3 protective film, which can protect the matrix from corrosion. By anodizing and coloring, the cast aluminum alloy with good casting performance or deformed aluminum alloy with good plasticity can be obtained.
5. Easy to process
After adding some alloy elements, the cast aluminum alloy with good casting properties or the deformed aluminum alloy with good plasticity can be obtained.
