1. The basic property of aluminum is silvery white, and it can form a layer of oxide film to prevent metal from corrosion in moist air. The relative density is 2.7 g/cm3, the melting point is 660 °c, the boiling point is 2327 °c, the specific strength is high, and it has good conductivity and thermal conductivity, high reflectivity and oxidation resistance. Second, the type of material categories: aluminum profile, aluminum pipe, aluminum bar and other plate categories: Aluminum Plate, aluminum foil, aluminum strip (coil) casting category: Aluminum Casting, aluminum grain three, commonly used brand (extended reading: Aluminum and Aluminum Alloy eight series number, suddenly become an aluminum expert!) The first digit of the brand represents aluminum alloy series, the second digit represents the original aluminum alloy modification, the last two digits indicate the purity of the aluminum alloy in the same group. 1100: for Processing requires good formability and high corrosion resistance, but does not require high-strength parts and components. Such as storage containers, sheet metal parts, deep-drawing concave utensils, heat exchangers, printing plates, nameplates, reflective appliances, etc. . 2011: fast-cutting Alloy, good machinability and high strength, but poor corrosion resistance, suitable for volume shafts, optical components, screws, screws and mechanical products requiring good machinability. 3003: The properties of the 1xxx series alloy are higher than those of the 1xxxx series alloy, such as kitchen utensils, food and chemical products processing and storage devices, tanks and tanks for transporting liquid products, and various pressure vessels and pipes for sheet metal processing. 4A01: High Silicon content, heat resistance, wear resistance, construction materials, mechanical parts, forging materials, welding materials. 5052: The most representative alloy of medium strength (5083 is the highest) , good corrosion resistance, solubility and formability, especially high fatigue strength, good sea water resistance, used for manufacturing aircraft fuel tanks, fuel pipes, and sheet metal parts for traffic vehicles and ships, instrument, street lamp bracket and rivets, hardware products, etc. . 6061: heat treated corrosion resistant alloy. The T6 treatment has very high endurance values, but low strength of solution joints, so it is suitable for screws, ships, vehicles, land structures. 6N01: Medium Strength extrusion alloy for large thin meat profiles with complex shapes. Excellent corrosion resistance and solubility. Applicable to vehicles, land structures, ships. 6063: Representative Alloy for extrusion, low strength than 6061, good extrudability, can make complex section shape profile, corrosion resistance and surface treatment are good, suitable for construction road guardrail, vehicles, furniture, household appliances, decorations. 7072: Low electrode potential, mainly used for anti-corrosion covering leather, heat sink of heat exchanger, aluminum foil of air conditioner and extra thin strip. 7075: Aluminum Alloy has the highest strength of the alloy, but poor corrosion resistance, with 7072 cover leather can improve its corrosion resistance, but the cost increases. For aircraft, Ski Poles, planks, forgings. MATERIAL SELECTION EXAMPLE: product requirements are relatively hard, surface treatment for coarse wire drawing or sand surface, choose to use 5000 series aluminum alloy, commonly used: 5052 product surface treatment requirements are high, can not have sand hole, profile marks, choose 6000 series aluminum alloy, commonly used: 6063/6061 products require low price, need to stretch the body review, choose to use 2000 series pure aluminum, commonly used: 2011 products high strength, high hardness, need to bear the structure, choose 7000 Series Aluminum Alloy, common use: 7075th, aluminum surface treatment (extended reading: Aluminum surface treatment process overview)1, sandblasting or drawing after anodizing 2, electrophoretic paint 3, after polishing powder electrostatic spraying, fluoro-carbon spraying 4, electroplating after Polishing Mirror 5, wood grain heat transfer 6, polymer PVC COATING 5, aluminum profile aluminum is aluminum bar through hot melt, extrusion, thus get different cross-section shape of aluminum pipe materials. Molding process mainly includes melting and casting, extrusion, cutting, CNC washing and cutting, surface pretreatment, coloring, 5 processes. Titanium plating and electrophoretic process are the most expensive, followed by wood grain heat transfer, anodizing, and finally spraying. The specific price is subject to the manufacturer's quotation. Aluminum profile has the following main applications: 1, building aluminum profile (doors, windows, curtain wall)2, radiator aluminum profile 3, General Industrial Aluminum Profile: mainly used in industrial production manufacturing, such as automatic machinery equipment, skeleton, can open-die customization. 4. Aluminum Alloy profiles for railway vehicle structure: mainly used for manufacturing of railway vehicle body. 5, decorate aluminum profile, make aluminum alloy face frame, mount all kinds of decorative painting. 6, the appearance of aluminum profile, mainly used in household appliances or communication industry, such as mobile hard disk, mobile power supply, television, display and other internal structure and appearance decoration. Aluminum Sheet (aluminum sheet)0.15-2.0 mm conventional sheet (aluminum plate)2.0-6.0 mm medium plate (aluminum plate)6.0-25.0 mm thick plate (aluminum plate)25-200 mm super-thick sheet (200 mm or more) single-layer aluminum plate can be used for electronic product shell, electrical appliance product shell or internal heat conduction parts. Aluminum Shell is finished by metal stamping die stretch molding, surface pretreatment, coloring, 3 processes completed. Polymer Film Aluminum Plate Molding Gradient Requirements, not easy to stretch, materials should not be corrosion, ultra-weatherability, color diversity, easy maintenance, etc. . Suitable for electronic products Shell, home appliance Shell and so on aluminum-plastic Composite Board is treated by the surface and with coating paint as the surface, polyethylene, polypropylene plastic mix as the core layer, after a series of processing composite materials. The utility model can be applied to the decoration of curtain walls, inner and outer walls, vestibule, restaurant, shop, meeting room, etc. . It can also be used for the reconstruction of old buildings, the surface layer of counters, furniture, the inner and outer walls of vehicles, etc. . The honeycomb aluminum plate adopts the compound honeycomb structure, which is formed by hot pressing the pre-formed box-shaped Panel and back board with the aluminum alloy honeycomb core material. It is suitable for curtain wall decoration, ceiling ceiling, bus, train, Metro and rail vehicles, commercial vehicles and container car bodies, ship building, billboard, interior decoration works. Decorative aluminum products with a high tensile surface, materials generally used 0.4-0.8 mm thickness, grade 6063/6061 or pure aluminum series. With aluminum functional Shell, there is a bottom tension, bending structure, the material generally used 0.8-1.2 thickness, choose a harder brand 5052/7075, or a special brand. With aluminum do on the shell of electronic products, need radium oxide layer to do conductive grounding, because after anodizing oxide layer is not conductive. 7. Aluminum alloy die casting aluminum alloy die casting in the structural design of the structure as little as possible to design the slanting roof structure, to prevent the follow-up to Burr is very difficult. When designing the structure of aluminum alloy die casting, it is necessary to pay attention to the average glue thickness and smooth flow of the glue, which can reduce many problems such as bad appearance caused by molding, and increase the follow-up polishing review. If you choose a relatively soft brand, then in the design of load-bearing structure, or need to consider the structural strength, otherwise easy to break.
