Overview: light non-ferrous metals non-ferrous material density of less than 4.5g / cm3 to find Brose, including pure metals and their alloys of aluminum, magnesium, sodium, potassium, calcium, strontium, barium. The common feature of such metals are: density (0.53 ~ 4.5g / cm3), small chemical activity, with oxygen, sulfur, carbon and a halogen compound are quite stable. Which is the most widely used application in the industrial aluminum and aluminum alloy, its production has more than 1/3 of the total production of non-ferrous materials.

 The major alloying elements in the 6000 series aluminum alloy 6061 aluminum bits represented as magnesium and silicon, with moderate strength, good corrosion resistance, weldability, oxidation is better. Widely used in certain strength and high corrosion resistance of a variety of industrial structural parts, such as the manufacture of trucks, tower building, ship, trams, railway vehicles, furniture, etc. is required. Edit this paragraph chemical composition of the main chemical components: copper (Cu): 0.15 to 0.4 Manganese Mn: 0.15 Mg Mg: 0.8 to 1.2 6061 aluminum tubes 
 Zinc Zn: 0.25 chromium Cr: 0.04 to 0.35 titanium Ti: 0.15 Silicon Si: 0.4 to 0.8 iron Fe: 0.7 aluminum Al: margin Edit this paragraph classification magnesium and silicon as the main alloying elements and the four-digit Mg2Si phase of strengthening phase aluminum alloy. The first one is a number to distinguish between groups. After two used to differentiate between the grades of the material within the series of the same group, there is no special significance. Four-digit system, and four character system grades the first number indicates the category of aluminum and aluminum have the following meanings: 1) 1XXX series of commercially pure aluminum; 2) 2XXX series Al-Cu, Al-Cu-Mn alloy 3) 3XXX series Al-Mn, can be processed pure aluminum; 4) 4XXX series Al-Si alloy; 5) 5XXX series Al-Mg alloy; 6) 6XXX series Al-Mg-Si alloy; 7) 7XXX series Al-Zn-Mg- Edit this section aluminum alloy 6061 Introduction Cu alloy; 
 6061 case the heat treatment may be strengthened alloy, has a good formability, weldability, machinability and, while having a moderate intensity, after the annealing can still maintain good operability. 6061 alloy major alloying elements are magnesium and silicon, and the formation of the Mg2Si phase. If they contain a certain amount of manganese and chromium, and iron, the bad effect; sometimes also by adding a small amount of copper or zinc in order to improve the strength of the alloy, without their corrosion resistance decreased significantly; conductive material, there is a small amount copper, to offset the adverse effects of titanium and iron conductive; zirconium or titanium grain refinement and control recrystallization organizations; can be added in order to improve the available cutting performance, lead and bismuth. Mg2Si solid solution in the aluminum, the alloy artificial age hardening function. 6061-T651 6061 alloy alloy heat treated pre-stretching process to produce high-quality aluminum alloy products, although its strength can not be compared with the the 2XXX Department or 7XXX Department, magnesium, silicon alloy processing performance excellent, excellent welding characteristics and plating, good corrosion resistance, high toughness and processing is not deformed material dense defect-free and easy polishing, color film is easily oxidized with excellent results and other fine features. 
 Typical use 
 First, the application of the strip are widely used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons, and other industries. Aerospace for the production of aluminum aircraft skins, fuselage frames, girders, rotors, propellers, fuel tank, siding and landing gear strut and rocket forging ring, spacecraft siding and other. Transportation, aluminum used in cars, subway cars, railway passenger cars, pieces of material of the body structure of the high-speed passenger train, car doors and windows, shelves, automotive engine parts, air conditioners, radiators, body panels, wheels and ships timber. Package pot material aluminum-aluminum cans mainly in the form of sheet and foil as metal packaging materials made of cans, cap, bottles, buckets, packaging foil. Widely used in beverage, food, cosmetics, drugs, cigarettes, and industrial products packaging. , Printing of aluminum is mainly used for production of the PS version, the aluminum base PS version of the printing industry, a new material for automated platemaking and printing. Architectural decoration aluminum alloy because of its good corrosion resistance, sufficient strength, excellent process performance and welding performance, mainly widely used in the framework of a building, the doors and windows, ceiling, decorative surface. Such as building windows and doors, curtain wall aluminum, aluminum curtain wall plate, pressure plate, checkered plate, color coated aluminum sheet. Electronic appliances mainly used with aluminum various bus, stringing conductors, electrical components, refrigerator, air conditioning, cable and other fields. Specifications: round, square bars represent uses include aerospace fixtures, electrical fixtures, communications, and is also widely used in automated machinery parts, precision machining, mold making, electronics and precision instruments, SMT, PC board solder vehicles, etc..
