1.The thermal technology of the 5052 aluminum sheet is excellent in plasticity. The temperature of casting and forging is 420~475 degree C, and the thermal deformation of >80% is carried out in this temperature range.
2.The cold stamping function is related to the condition of aluminum sheet. The cold stamping function of annealing (O) condition is outstanding, followed by H32 and H34 condition, while H36/H38 condition is not good.2. Welding function(1) The aluminum sheet has outstanding functions of gas welding, arc welding, resistance welding, spot welding and seam welding, and tends to crystallize cracks during DIG welding. The brazing function is good while the soldering function is poor.(2) the strength and plasticity of the weld are high, and the strength of the weld is 90%~95% of the base metal strength. But the air tightness of the weld is not high. 5A03 aluminum plate is recommended as the welding material, which can improve the air tightness and eliminate the crack tendency.Machining functionThe anneal condition of the aluminum plate is not good, while the cold hardening condition is improved.
