1. How many series of aluminum alloy?
1000 series (pure aluminum, with at least 99% aluminum content): belongs to a series with the most aluminum content. Used in conventional industry.
2000 series (mainly copper alloy): high hardness, with the highest content of copper element, about 3-5%, used in the aviation field.
3000 series (mainly manganese): content between 1.0-1.5, used for the industry and products with high requirements for rust prevention.
4000 series (mainly silicon): content between 4.5-6.0%. Construction materials, mechanical parts, forging materials, welding materials; Low melting point, good corrosion resistance, heat and wear resistance.
5000 series (mainly magnesium): belongs to the more commonly used alloy aluminum plate series, the main characteristics are low density, high tensile strength, high elongation, good fatigue strength, but cannot do heat treatment strengthening. It is also widely used in conventional industry.
6000 series (mainly magnesium and silicon): mainly contains magnesium and silicon, suitable for corrosion resistance, high oxidation requirements of the application.
7000 series (mainly zinc): belongs to aviation series, is aluminum magnesium zinc copper alloy, is heat treatment alloy, belongs to super hard aluminum alloy, has good wear resistance, also has good weldability, but poor corrosion resistance.
8000 series (other elements): Among the 8000 series aluminum alloys, 8011 is more often used for us. It is mostly used to produce aluminum foil and not commonly used in the production of aluminum rods.
2. Features of 3000 series aluminum plate
3000 series aluminum plate, it is aluminum manganese alloy aluminum plate, because of manganese alloy elements, aluminum plate has excellent rust resistance, also known as rust resistance aluminum plate this alloy strength is not high, so it cannot be strengthened by heat treatment, so the method of cold processing to improve its mechanical properties.
Mechanical properties High plasticity in annealing state, good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability but poor cutting performance. This series of aluminum plate is commonly used in outer packaging, mechanical parts, air conditioning ventilation pipes and other humid environment, so its high-temperature resistant products have good rust resistance.
3. The use of 3000 series aluminum
3A21 chemical composition used in aircraft fuel tank, oil conduit, rivet wire, etc. Building materials and food and other industrial equipment.
3003 Chemical components such as kitchen utensils, food and chemical product processing and storage devices, liquid product transport tanks, various pressure vessels and sheet metal processing pipes.
3A21 can be used for machinery and equipment manufacturing and industrial machinery and equipment frame, medical equipment, office equipment; Furniture, guardrail all kinds of structural parts.
3004 is suitable for aluminum cans, parts with strength higher than 3003 alloy, chemical production and storage devices, plate processing parts, building processing parts, building tools, various lamp parts.
3005 is suitable for room partition baffle, movable room board, cornice, downpipe, sheet metal forming workpiece, bottle cap, cork, etc.
4. Differences between 3000 series and 5000 series aluminum
(1). Different chemical composition
3000 series aluminum is mainly composed of aluminum-manganese alloy, and the main grades are 3003 and 3A21. 5000 series aluminum is mainly composed of aluminum-magnesium alloy, and the commonly used grades are 5052, 5083 and 5754
(2). Different performance
3000 series aluminum has good rust resistance, good formability, high corrosion resistance and high strength. 5000 series aluminum material of light weight, high strength, corrosion resistance, easy to color, and has the characteristics of low density, good heat dissipation, strong compression.
(3). Different applications
3000 series aluminum material is used in the need of anti-corrosion, anti-rust performance, such as pipe insulation, cold storage ground skid construction. 5000 series aluminum is more widely used in manufacturing industry, such as aircraft, automobile, radiator and so on.
