Marked with underscore.
The chemical composition and mechanical property of each aluminum alloy plate materials in the embodiment of table 6 and comparative example
As can be seen from Table 6：The mechanical property of aluminum alloy plate materials in embodiment 1-3 is in the feature mechanical property of the present invention
In energy range, and substantially lower than the intensity of tinplate, elongation percentage is high, for food cans to be manufactured process highly beneficial.
And the mechanical property of the aluminum alloy plate materials in comparative example 1-3 not the present invention feature mechanics performance range in, reason is as follows：
Comparative example 1 causes yield strength and tensile strength after sheet material baking to be unsatisfactory for spy of the invention because of Cu too high levels
Levy requirement；Comparative example 2 causes yield strength and tensile strength after sheet material baking to be unsatisfactory for feature of present invention because of Mn too high levels
It is required that；Comparative example 3 is too low because of Mg contents, cause sheet material toast after yield strength and tensile strength be unsatisfactory for feature of present invention will
Ask.
Therefore, the alloying element composition of only aluminum alloy plate materials is corresponding in the alloying element compositing range of the present invention
The mechanical property of aluminum alloy plate materials could in the feature mechanics performance range of the present invention, could meet user for easy-open end or
The particular requirement that draw ring is pressure-resistant.The embodiment of the present invention passes through the accurate control to alloying component so that the food cans produced are used
Aluminium alloy plate further improves the elongation percentage of sheet material, so as to obtain on the premise of ensureing that tensile strength and yield strength are enough
More preferably processability.
Test example 2 compares according to the mechanical property of aluminum alloy plate materials made from different technical parameters
This test example is compared there is provided comparative example 4-7 and embodiment 6-9.In order to simplify description, with the conjunction of embodiment 6
Golden component is A alloys, and using the alloy compositions of embodiment 8 as B alloys, each element content of A alloys and B alloys is shown in Table 7.
