The advantages of industrial aluminum profiles are as follows:
Strength: strength is an important factor that must be considered in product design. It is an aluminum alloy part. As a part, the appropriate alloy shall be selected according to the pressure. The strength of pure aluminum is lower, while the hardness of the 2 - and 7 - series heat treated alloys is higher.
Hardness: Many customers are very concerned when purchasing aluminum. The hardness is directly related to the chemical composition of the alloy. Secondly, different states also have a great impact on the hardness. From the point of view of the achievable hardness, 7 series, 2 series, 4 series, 6 series, 5 series, 3 series and 1 series decreased successively.
Corrosion resistance: corrosion resistance includes chemical corrosion resistance, stress corrosion resistance, etc. In general, 1-series pure aluminum has good corrosion resistance, 5-series is good, 3-series and 6-series are next, and 2-series and 7-series are poor. The selection principle of corrosion resistance shall be based on its application. When high-strength alloy is used in corrosive environment, various anti-corrosion composite materials must be used.
Weldability: Most aluminum alloys have no problems in weldability, especially some 5 series aluminum alloys are specially designed for welding. In contrast, some Series 2 and 7 aluminum alloys are difficult to weld.
Decorative performance: When aluminum profiles are used for decoration or some special occasions, they need to be anodized and coated to obtain the corresponding color and surface structure. At this time, decoration should be considered. Generally speaking, materials with good corrosion resistance have excellent anodic treatment performance, surface treatment performance and coating performance.
Machinability: Machinability, including formability and machinability. As formability is related to state, strength range of various states shall be considered. Generally speaking, high-strength materials are not easy to form. Taikoo aluminum materials need to undergo bending, stretching, drawing and other forming processes, and the formability of annealed materials is better than that of heat treated materials. The machinability of aluminum alloy is poor, and the machinability of mold and mechanical parts is good. On the contrary, the processability of low strength products is poor. Machinability of aluminum alloy is an important consideration for mold and machine parts. The advantages of industrial aluminum profiles are introduced.
