Beijing trillion promise Trading Company Materials: aluminum and aluminum alloy extruded bars (≤ 150mm, H112, T6, O-state) standard: GB/T3880-2006 characteristics and scope of application: ① 5052 belongs to the Al-Mg alloy, use a wide range, especially in the construction industry can not do without this alloy is the most promising alloy. Good corrosion resistance, weldability, and good cold workability, and having a medium strength. 5052 major alloying elements magnesium, has good forming properties, corrosion resistance, weldability, medium strength, used in the manufacture of aircraft fuel tanks, tubing, and transport vehicles, the sheet metal of the ship, instrumentation, lights bracket with rivets metal products, electrical - shell. ② AL-Mn-based alloys, the most widely used of a rust-proof aluminum, high strength of this alloy, especially with anti-fatigue strength: high plasticity and corrosion resistance, heat treatment can not be strengthened, in the semi-cold-hardening plastic still good, low plasticity in the cold hardening, good corrosion resistance, good weldability, poor can machinability, can be polished. Uses mainly used require high plasticity and good weldability, the low load part of the liquid or gaseous medium in the work, such as tanks, gasoline or oil conduit, a variety of liquid container, and produced by deep drawing a small load Part: wire used to make rivets chemical composition of 5052 aluminum chemical composition: Al Al: margin silicon Si: ≤ 0.25 Copper Cu: ≤ 0.10 Mg: 2.2 to 2.8 Zinc Zn: ≤ 0.10 Manganese Mn: ≤ 0.10 Chromium Cr: 0.15 to 0.35 iron Fe: ≤ 0.40 Note: single: ≤ 0.05; Total: ≤ 0.15 density 2.72g/cm3 mechanical properties mechanical properties: tensile strength σb (MPa) 173 ~ 244 conditions yield strength σ0.2 (MPa) ≥ 70 density 2.68 g / cubic centimeter sample size: all wall thickness Note: The performance of different states of the pipe longitudinal mechanical properties at room temperature. The surface of the surface does not allow cracks, corrosion spots and nitrate traces. 2, the surface allows the depth does not exceed the defect site where the wall thickness of the nominal size of 8% from the skin, bubbles, surface roughness ultrasound and local mechanical damage, the the defect maximum depth can not exceed 0.5 mm defect does not exceed the total area of ??sheet total area of 5%. 3, allows the supplier along the the profile vertical lighting to smooth surface. 4 Other requirements: the demand side and the supply side intended, aluminum surface glossy, no scratches, the machine pressure from the board rarely have collections of capsules. Heat treatment process) homogenizing annealing: heating 440 ° C; thermal insulation of 12 ~~ 14h; air cooling. 2) rapid thermal annealing: heating 350 ~ 410 ℃; holding time of 30 to 120min; empty or water-cooled. 3) high-temperature annealing: heating to 350 ~ 420 ℃; the finished thickness ≥ 6mm or <6mm holding time of 2 ~ 10min or 10 ~ 30min; air cooling. 4) low temperature annealing: heating to 250 ~ 300 ℃ or 150 to 180 ° C; holding time of 1 ~~ 2h, air-cooled.
