What are the characteristics of each series of aluminum plates?(Part Ⅱ)
5 series: ① 5XXX series are high-magnesium alloys (5A06 (LF6) 5A05 (LF5), which have good strength, corrosion resistance and machinability among non-heat-treatable alloys. The surface is beautiful after anodizing treatment. The arc welding performance is good. 5XXX series The main alloying element in the alloy is magnesium, which has good corrosion resistance, weldability, and medium strength. Excellent corrosion resistance makes 5XXX series alloys widely used in marine applications such as ships, as well as automobiles, aircraft weldments, subway light rails , Pressure vessels that require strict fire protection (such as liquid tankers, refrigerated trucks, refrigerated headers), refrigeration devices, TV towers, drilling equipment, transportation equipment, missile parts, armor, etc.
②5XXX series belongs to Al-Mg-Si series alloys, which are widely used, especially the construction industry cannot do without this alloy, and it is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability, and medium strength. The main alloying element of 5XXX series is magnesium, which has good formability, corrosion resistance, weldability, and medium strength. It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts of transportation vehicles and ships, instruments, street lamp brackets and rivets. , hardware products, electrical enclosures, etc.
③ AL-Mn series alloy is the most widely used anti-rust aluminum. This alloy has high strength, especially fatigue resistance: high plasticity and corrosion resistance, and cannot be strengthened by heat treatment. Good plasticity, low plasticity when cold work hardening, good corrosion resistance, good weldability, poor machinability, and can be polished. Mainly used for low-load parts that require high plasticity and good weldability, working in liquid or gaseous media, such as mailboxes, gasoline or lubricating oil conduits, various liquid containers and other small-load parts made by deep drawing: The wire is used to make rivets.
6 Series: The main alloying elements of the 6XXX series alloys are magnesium and silicon AlMgSi1Cu and form the Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance; there is also a small amount of conductive materials Copper can be used to offset the adverse effects of titanium and iron on conductivity; zirconium or titanium can refine grains and control recrystallization structure; in order to improve machinability, lead and bismuth can be added. The solid solution of Mg2Si in aluminum makes the alloy have the function of artificial age hardening.
7 series: ① 7000 aluminum alloy is another commonly used alloy with various varieties. It contains zinc and magnesium. Among the more common aluminum alloys, the strongest strength is 7075 alloy, but it cannot be welded, and its corrosion resistance is quite poor. Many parts manufactured by CNC cutting use 7075 alloy. Zinc is the main alloying element in this series, and the addition of a small amount of magnesium alloy allows the material to be heat treated to achieve very high strength characteristics. These series of materials are generally added with a small amount of alloys such as copper and chromium, among which the number 7075 aluminum alloy is particularly top-grade, with the highest strength, suitable for aircraft frames and high-strength accessories.
② 7075 belongs to Al-Zn-Mg-Cu super duralumin. This alloy has been used in the aircraft manufacturing industry in the late 1940s and is still widely used in the aviation industry. It is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150°C, and particularly good low-temperature strength; poor welding performance; tendency to stress corrosion cracking; need to be coated with aluminum or other Protected processing use. Dual-stage aging can improve the alloy's ability to resist stress corrosion cracking. The plasticity in the annealed and just-quenched state is slightly lower than that of 2A12 in the same state. Slightly better than 7A04, the static fatigue of the plate is sensitive to notches, and the stress corrosion performance is better than 7A04.
8 series: 8011 is more commonly used and belongs to other series. In my memory, the aluminum plate is mainly used as a bottle cap, and it is also used in radiators, most of which are aluminum foil. Not very commonly used. Aluminum rod specifications: maximum diameter: 500mm.
