What should be considered in the strength design of industrial aluminum?

1. Hardness: Many customers are very concerned when buying aluminum, and the first choice of hardness is directly related to the chemical composition of the alloy. Secondly, different states also have great influence. The highest hardness that can be reached decreases in order of 7 series, 2 series, 4 series, 6 series, 5 series, 3 series and 1 system. That is to say, the hardness of aluminum profiles made of pure aluminum is very low.

2. Strength: Strength is an important factor that must be considered in product design. When it is an aluminum alloy component, the appropriate alloy should be selected according to the pressure. The strength of pure aluminum is the lowest, while the alloying degree of heat treatment series 2 and 7 is the highest, and there is a certain correlation between hardness and strength.

3. Corrosion resistance: Corrosion resistance includes chemical corrosion resistance and stress corrosion resistance. Generally speaking, the corrosion resistance of 1 system pure aluminum is the best, and the performance of series 5 is better, followed by series 3 and 6, and series 2 and 7 are worse. The selection principle of corrosion resistance should be determined according to its application. When high strength alloy is used in corrosive environment, various composite materials must be used for anticorrosion.

4. Machinability: Machinability includes formability and machinability. Because the formability is related to the state, the strength range of various States should be considered after choosing the aluminum alloy brand. Generally, materials with high strength are not easy to form. If aluminum is to be bent, stretched and deep drawn, the formability of annealed materials is the best, whereas the formability of heat-treated materials is the worst. The machinability of aluminum alloy is poor, so it is better for molds and mechanical parts. On the contrary, the machinability of low-strength products is poor. Machinability of aluminum alloy is an important consideration for products that need to be processed, such as molds and mechanical parts.

5. Weldability: Most aluminum alloys have no problem in welding, especially some 5-series aluminum alloys, which are specially designed for welding. Relatively speaking, some 2-series and 7-series aluminum alloys are difficult to weld.

6. Decorative performance: When aluminum is used for decoration or some special occasions, it needs anodizing and painting to obtain the corresponding color and surface texture. At this time, it is necessary to focus on its decorative performance. Generally speaking, materials with good corrosion resistance have excellent anodic oxidation performance, surface treatment performance and coating performance. The above points are the focus of purchasing aluminum profiles, and as our industrial aluminum profiles, they are all used in machinery, assembly line equipment, conveyors and so on. It requires all aspects of aluminum profiles to be comprehensive, so basically the profiles produced by 6063-T5 series aluminum are the most suitable.
