Aluminum, with aluminum or aluminum alloy is the processed material is made (cut or sawn) is obtained through the pressure cross-section is rectangular, rectangular material having a uniform thickness international customary to more than 0.2mm in thickness, 500mm or less, 200mm width over the length of 16m within the aluminum material called aluminum sheet or aluminum sheet, 0.2mm or less as aluminum foil, a width of less than 200mm exhaust material or strip (of course, with the progress of large equipment, can be the most wide-600mm The row material will be more). Uses: 1 2 lighting, solar reflective film 3, 4 building exterior, interior decorating: Ceilings, walls, etc. 5, furniture, cabinets, 6, 7 lifts, signs, nameplate, bags 8, 9 upholstery automotive interior and exterior decoration : If 10 frames, household appliances: 11 aerospace and military aspects refrigerators, microwave ovens, audio equipment, such as China's large aircraft manufacturing, the Shenzhou series of spacecraft, satellites and so on. 12, machine parts 13, 14 mold manufacturing, chemical / thermal insulation pipe coating. 50,525,052 process performance ⑴ formability of aluminum alloy thermal process ① good plasticity. Forging and die temperature of 420 ~ 475 ° C, the deformation in this temperature range> 80% of the thermal deformation. ② cold stamping its performance and state of the alloy, good performance of cold stamping annealed (O) state, while H32, H34 state followed while H36/H38 bad state. ⑵ ① weldability of the alloy welding, arc welding, resistance welding, spot welding, seam welding good performance, crystalline cracks tend to occur when two welding. Brazing of performance is still good, and the soldering performance is poor. ② high strength and ductility of the weld, 90% to 95% of the strength of the weld metal strength Scientology. But not high airtight weld, solder alloy as recommended 5A03, which can improve the air tightness, the disease tends to eliminate the cracks. ⑶ good machining properties of the alloy in the annealed condition of cutting performance, while some changes are summarized 5052 aluminum alloy Al-Mg alloy when cold cherry state, using a wide range, especially in the construction industry can not do without this alloy is The most promising alloys. Good corrosion resistance, weldability, good cold workability, and with moderate strength. The main alloying elements magnesium aluminum alloy 5052, has good forming properties, corrosion resistance, weldability, moderate intensity, for the manufacture of aircraft fuel tanks, fuel lines, and transportation vehicles, ship sheet metal parts, instruments, lights bracket and rivets, metal products, electrical - housing and so on. 5052 aluminum is the most widely used as a rust-proof aluminum, high strength of this alloy, especially with anti-fatigue strength: high plasticity and corrosion resistance, heat treatment can enhance the work hardening plasticity half is still good, cold hardening low plasticity, good corrosion resistance, good weldability, machinability bad, can be polished. Uses mainly used for high plasticity and good weldability, working in a liquid or gaseous medium low load parts, such as fuel tanks, gasoline or oil conduit, and a variety of other liquid containers produced by deep drawing a small load parts: wire used to make rivets. Chemical composition of aluminum Al: margin silicon Si: ≤ 0.25 Copper Cu: ≤ 0.10 Mg Mg: 2.2 ~ 2.8 Zinc Zn: ≤ 0.10 Manganese Mn: ≤ 0.10 Chromium Cr: 0.15 ~ 0.35 Iron Fe: ≤ 0.40 Note: Individual: ≤ 0.05 ; Total: ≤ 0.15 density is 2.72g/cm mechanical properties of tensile strength σb (MPa) 173 ~ 244 Conditions yield strength σ0.2 (MPa) ≥ 70 Density 2.68 g / cc Sample Size: All Thickness Note: Pipe longitudinal mechanical properties at room temperature
