profiles cover a very wide range and can be seen almost everywhere, especially in the construction industry. With the development of science and technology, the types of aluminum
profiles continue to increase and each has its own characteristics. Then, how should we choose? Below, the editor will lead you to understand the factors that affect the selection of industrial aluminum profile profiles and the selection methods: 一, Strength: Strength is an important factor considered in product design. When it is made of aluminum alloy components as components, the appropriate alloy should be selected according to the pressure it bears. Pure aluminum has the lowest strength, while the 2 series and 7 series heat-treated alloys have the highest degree. There is a certain relationship between hardness and strength. 2. Hardness: Many customers are very concerned when buying aluminum. The first choice of hardness is directly related to the chemical composition of the alloy. Secondly, different conditions also have a greater impact. From the perspective of the highest achievable hardness, the 7 series, the 2 series, the 4 series, the 6 series, the 5 series, the 3 series and the 1 series are sequentially reduced. 3. Corrosion resistance: Corrosion resistance includes chemical corrosion and stress corrosion resistance. Generally speaking, pure aluminum of series 1 has the best corrosion resistance, series 5 performs well, followed by series 3 and 6, and series 2 and 7 are inferior. The selection principle of corrosion resistance should be determined according to its use occasion. For high-strength alloys to be used in a corrosive environment, various anti-corrosion composite materials must be used. 4. Weldability: There is no problem with the weldability of most aluminum alloys, especially some 5 series aluminum alloys, which are specially designed for welding considerations. On the contrary, some 2 series and 7 series aluminum alloys are difficult to weld. 5. Decorative performance: When aluminum is used for decoration or some specific occasions, the surface needs to be processed by anodizing and painting to obtain the corresponding color and surface structure. At this time, its decorative properties should be considered. Generally speaking, materials with better corrosion resistance have very good anodic treatment performance, surface treatment performance and coating performance. 6. Machinability: Machinability includes insert forming performance and cutting performance. Because formability is related to state, after selecting aluminum alloy grades, the strength range of various states must be considered. Generally, high-strength materials are not easy to form. Taiguo needs to bend, stretch, and deep-draw the aluminum material. The formability of the material in the annealed state is good. On the contrary, the formability of the heat-treated material is the worst. Aluminum alloy has poor machinability and better machinability for molds and mechanical parts. On the contrary, low-strength ones have poor machinability. For products that require cutting, such as molds and mechanical parts, the machinability of aluminum alloy is important. Consider factors. The above is the selection method of industrial aluminum profile profile that I brought you.
