Embodiment 1

[0023] This embodiment proposes an aluminum alloy, including Fe: 0.30-0.50 parts; Si: 0.10-0.30 parts; Cu: 0.05-0.20 parts; Mn: 0.05-0.25 parts; Mg≤0.05 parts; Zn≤0.05 parts; : 0.010-0.035 parts; the balance is aluminum Al; wherein, the ratio range of Fe and Si is 1:1-5:1.

[0024] The aluminum alloy proposed in this embodiment is based on the improvement of pure aluminum 1060. On the basis of pure aluminum 1060, the proportion of some elements is changed, and new elements are added to improve the performance of the aluminum alloy. As a preference, the ratio of Fe and Si can be controlled between 2 to 1 to 2.5 to 1. Compared with pure aluminum 1060, adjusting the ratio of Fe and Si in this embodiment can reduce the ear making rate and further improve the tensile strength. extensibility. The ratio of Fe and Si is controlled in the range of 1:1-5:1, specifically, 1, 1.5, 1.6, 1.8, 2, 2.1, 2.7, 2.5, 3.0, 5.0, 4.3, 4.8, 4.0, 4.3, 4.9, Values ​​such as 3.7, 3.4, 3.5, 3.9, 3.2, 3....

Embodiment approach

[0035] Fe: 0.42 parts; Si: 0.21 parts; Cu: 0.14 parts; Mn: 0.09 parts; Mg: 0.01 parts; Zn: 0.01 parts; Ti: 0.010 parts; the balance is Al.

[0036] Fe: 0.46 parts; Si: 0.23 parts; Cu: 0.16 parts; Mn: 0.11 parts; Mg: 0.04 parts; Zn: 0.04 parts; Ti: 0.035 parts; the balance is Al.

[0037] Fe: 0.44 parts; Si: 0.22 parts; Cu: 0.15 parts; Mn: 0.1 parts; Mg: 0.03 parts; Zn: 0.03 parts; Ti: 0.02 parts; the balance is Al.

[0038] It is conceivable that the elements of each component can be appropriately adjusted according to the actual processing requirements. Compared with pure aluminum 1060, the element combination falling within the scope of this embodiment has little change in elongation, but the tensile strength has been improved, and has a more good performance.

Embodiment 2

[0040] This example proposes a processing technology for aluminum shells. The above-mentioned aluminum alloy is blended and melted. After refining, slag removal and online degassing, it is cast and rolled into billets, and the billets are cold-rolled and then annealed at high temperature. , After cooling, it is rolled into a finished aluminum shell, and the finished aluminum shell is annealed at low temperature, and then cut.

[0041]An aluminum shell processing process in this embodiment uses the above-mentioned aluminum alloy components to produce an aluminum alloy shell with good tensile strength through processes such as batching, melting, blending, casting and rolling, cold rolling, heat treatment, and slitting. body, to be applied to the shell of electronic components, such as the capacitor shell, which can effectively improve the deformation resistance of the capacitor shell, effectively improve the problem of "bulging" of the capacitor, and prolong the service life of t...

technical field [0001] The invention relates to the technical field of metal processing, in particular to an aluminum alloy and aluminum shell processing technology. Background technique [0002] After the pure aluminum 1060 material is stretched into an aluminum shell, there are problems such as low tensile strength and low hardness, and the finished aluminum shell has defects such as easy deformation and bulging at the bottom of the aluminum shell; secondly, due to the Aluminum shells are mainly used for capacitors, which have high requirements for quality. Therefore, the capacity and explosion-proof pressure of aluminum shells also need to be considered. Aluminum shells made of existing aluminum alloy processing technology are bound to increase when the above requirements are met. The thickness of the material wall increases the production cost, and it is difficult to meet the user's requirements for aluminum shell products. Contents of the invention [0003] The techn...
