A5052-H32A5052-H32A5052-H32A5052-H32 Product Specifications: 5052 Aluminum Description: aluminum and aluminum alloy extruded bars (≤150mm, H112, T6, O state) Standard: GB / T3880-2006 Features and Scope: ① 5052 belonging to Al-Mg alloy, using a wide range, particularly in the construction inseparable from this alloy is the most promising alloys. Good corrosion resistance, weldability, cold is better, and with moderate intensity. 5052 is the main alloying elements of magnesium, has good forming properties, corrosion resistance, weldability, moderate intensity, for the manufacture of aircraft fuel tanks, pipelines, and transportation vehicles, ship sheet metal parts, instruments, lights bracket and rivets, metal products, electrical - housing and so on. ② AL-Mn alloy, is the most widely used as a rust-proof aluminum, high strength of this alloy, especially with anti-fatigue strength: high ductility and corrosion resistance, heat treatment can enhance the plastic work hardening in half still good, when the plastic work hardening is low, good corrosion resistance, good weldability, machinability bad, can be polished. Mainly used for high plasticity and good weldability, working in a liquid or gaseous medium low load parts, such as tanks, gasoline or oil conduit, and a variety of other liquid containers made by deep drawing of a small load parts: 5052 aluminum wire used to make rivets chemical properties: Al Al: margin silicon Si: ≤0.25 copper Cu: ≤0.10 magnesium Mg: 2.2 ~ 2.8 Zinc Zn: ≤0.10 Mn Mn: ≤0.10 chromium Cr: 0.15 ~ 0.35 iron Fe : ≤0.40 Note: Single: ≤0.05; Total: ≤0.15 density is 0.000272 5052 aluminum alloy physical properties: Tensile strength σb (MPa) 173 ~ 244 Conditions yield strength σ0.2 (MPa) ≥70 density of 2.68 g / cc Sample Size: All Thickness Note: Different vertical pipe at room temperature mechanical properties of the state of different properties. 5052 aluminum heat treatment process: 1) homogenization: Heat 440 ℃; holding 12 ~ 14h; air cooling. 2) rapid thermal annealing: heating 350 ~ 410 ℃; holding time 30 ~ 120min; air or water. 3) high temperature annealing: heating 350 ~ 420 ℃; finished thickness ≥6mm or <6mm, the holding time of 2 ~ 10min or 10 ~ 30min; air cooling. 4) low-temperature annealing: heating 250 ~ 300 ℃ or 150 ~ 180 ℃; holding time of 1 ~ 2h, air cooling.
