Embodiment approach 1
[0018] The aluminum alloy with medium mechanical strength and corrosion resistance has not more than 0.25 parts of silicon, not more than 0.35 parts of iron, 0.1 parts of copper, 0.1 parts of manganese, 0.2-0.3 parts of chromium, 2.3-2.6 parts of magnesium, 0.1 part zinc and 100 parts aluminum.
[0019] The above-mentioned aluminum alloy with medium mechanical strength and corrosion resistance has an internal metallographic structure: the phases precipitated along the grain boundaries are in the form of discontinuous points, and most of them are regular sub-grain boundaries, so as to avoid the occurrence of Mg between grain boundaries. 5 Chain distribution of Al phase.
Embodiment approach 2
[0021] The manufacturing method of the described aluminum alloy with medium mechanical strength and corrosion resistance:
[0022] a. Chemical composition: by weight percentage, the melt consists of not more than 0.25 parts of silicon, not more than 0.35 parts of iron, 0.1 parts of copper, 0.1 parts of manganese, 0.2-0.3 parts of chromium, and 2.3-2.6 parts of magnesium , 0.1 parts of zinc and the remaining parts of aluminum are put into a gas reverberatory furnace for smelting at a melting temperature of 700-750°C, and then transferred to a resistance reverberatory furnace to accurately adjust the chemical composition, and degassing and grilling Slag and other routine treatment;
[0023] b. Transfer the melt to a net furnace for casting. During casting, ceramic filtration method is used for melt purification treatment. Among them, the content of magnesium must be strictly controlled to 2.3-2.6 parts, the content of iron is about 0.35 parts, and the content of silicon is 0.25 ...
Embodiment approach 3
[0027] In the method for manufacturing an aluminum alloy with medium mechanical strength and corrosion resistance described in Embodiment 2, after the annealing, a stabilizing annealing treatment is performed according to the metallographic structure.
[0028] During the manufacturing process, through the lubrication control of hot rolling, defects in surface quality and end surface quality such as sticking aluminum can be avoided.
[0029] During the processing, the processing rate of Hln series products can be determined by performing 15-90% cold rolling deformation on the completely crystallized billet, testing the hardening curve and observing the polarized structure.
[0030] During the processing, the annealing temperature of the H2n series products is determined to be 210-270°C through the annealing softening test on the hardened products.
[0031] In the process of processing, through the annealing softening test and sensitization test of products in different hardenin...
