6061 aluminum Introduction is a heat treatment may be strengthened alloy, has a good formability, weldability and machinability performance, while having moderate intensity, after annealing, was able to maintain good operability 6061 alloy main alloying elements magnesium and silicon, and the formation of 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 uses a strip applications 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.. 6061 aluminum 6061 aluminum elements main alloying elements 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 aluminum alloy as the main alloying element is magnesium, and silicon and having a medium strength, good corrosion resistance, weldability, oxidation better. Characteristics of magnesia 6061 magnesia 6061-T651 is the 6 based alloy main alloying, heat treated aluminum alloy product of the pre-stretching process of high quality; magnesia 6061 having excellent processing properties, good corrosion resistance, high toughness, and processing after deformation, easy color film with excellent oxidation characteristics of the fine. Main purpose: Widely used requires a 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. The 6061 typical use on behalf of uses including 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 and so on. 6061 chemical ingredients copper Cu: 0.15 to 0.4 Manganese Mn: 0.15 Mg: 0.8 to 1.2 zinc Zn: 0.25 Chromium Cr: 0.04 to 0.35 titanium Ti: 0.15 Si Si: 0.4 to 0.8 Iron Fe: 0.7 Aluminum Al: remainder 6061 Mechanics The 6061 performance of the ultimate tensile strength of 124 MPa with material tensile yield strength of 55.2 MPa Elongation 25.0% coefficient of elasticity 68.9 GPa bending ultimate strength of 228 MPa the fatigue strength of 62.1 density 0.0000028 6061 Heat Treatment rapid annealing: heating temperature of 350 to 410 ° C; the difference in thickness, the holding time is between 30 ~ 120min; air or water cooled. 2) high-temperature annealing: heating temperature of 350 to 500 ° C; the finished thickness ≥ 6mm, the holding time of 30min <6mm heat through until; air cooling. 3) Low-temperature annealing: heating temperature of 150 to 250 ° C; holding time of 2 to 3h; air or water cooled.
